Strawberry cheesecake ice cream cake
Ingredients:
Graham Cracker Crust
6 tablespoons (85g) unsalted butter, melted
1 and 3/4 cups (209g) blended honey graham crackers (~12-13 full sheets of graham crackers)
1/4 cup (50g) white granulated sugar
1/2 teaspoon fine sea salt (or 1/4 teaspoon table salt)
Filling:
1/2 gallon (4 pints; 8 cups) strawberry ice cream (we love Tillamook's Oregon Strawberry)
1 (17 oz.; 481g) prepared frozen cheesecake Note 1
Optional toppings: spray whipped topping (or fresh whipping cream), fresh strawberries, or sugared strawberries (See Note 2)
Instructions:
GRAHAM CRACKER CRUST: Start by melting the butter in a microwave safe bowl. Once melted, set aside to cool to room temperature for 5 minutes. In a blender or food processor, place the graham crackers and process/blend until the crackers are all crumbs (re-blend any large chunks). Measure to get a level 1 and 3/4 cups of crumbs and add to a large bowl. Add in the sugar and salt. Use a spatula to scrape every bit of the melted, but cooled (hot butter will cause a greasy crust) butter into the bowl. Gently stir with a wooden spoon until well combined.
FORM CRUST: Dump the mixture into a 9-inch springform pan. Mainly press the crumbs into the bottom of the pan and then about 1/2 inch up the sides. Use the bottom of a flat 1 cup measuring cup to throughly compress the graham cracker crumbs into a firm crust. Place the pan in the freezer while you make the filling for the pie.
ICE CREAM: Allow the ice cream to soften for about 5-10 minutes depending on the temperature of your kitchen. (You don't want the ice cream to get too melty or it becomes icy when re-frozen.) Scoop ice cream into a very large bowl.
CHEESECAKE: Remove cheesecake from packaging and chop into 1/2-inch pieces. Add the cheesecake pieces right on top of the ice cream. Using a wooden spoon, gently mix until the ice cream and cheesecake pieces are integrated. Don't over-mix.
FINISHING PIE: Pour the mixture over your prepared graham cracker crust. Press down with the back of the wooden spoon into one even layer on top of the crust and then use a spatula to smooth the top. Cover tightly and put in the freezer to set at least 8 hours or until completely firm.
ENJOY: Once pie is firm, remove from springform pan and cut into slices (to get clean slices, run a large sharp knife under hot water for a few seconds, wipe to dry, make 1 slice, and repeat). Serve as is or with optional toppings: a spray of whipped topping or a doll-up of fresh whipped cream. Garnish with a fresh strawberry or sugared strawberries (See Note 2). Enjoy immediately. Do not add any optional toppings to slices that will be leftover. Promptly return leftovers, covered tightly, into the fre'd

The serious accident of Tiger Woods would be due to a "dangerous" speed of 140 km / h

noreply@blogger.com (sfdgd) — Tue, 30 Nov 2021 07:51:00 -0800

Tiger Woods car

The Los Angeles police have just released their findings while denying any preferential treatment in the investigation into the accident of the American star. He was driving at twice the authorized speed

The images had made the sports world shudder. Victim of a serious road accident on February 23, in Los Angeles, the American golfer Tiger Woods, the legend of his sport, would be responsible for this crash.

This Wednesday, after refusing to communicate at first, the police published their conclusions on this accident in which the golfer was seriously injured. He and his lawyers gave their consent.

According to the police, the loss of control and the numerous rollovers would be due to a "dangerous" speed of 140 km / h. In this section, the speed is limited to 70 km / h. "Dangerous speed for road conditions" is the cause of the crash that seriously injured Woods, 45, on February 23 in Rancho Palos Verdes, Sheriff Alex Villanueva told reporters.

Tiger Woods

He accelerated rather than brake

He also denied any special treatment of the star who had not been subjected to alcohol and drug tests. Authorities said the star told doctors responsible for caring for her broken right leg that she had not consumed alcohol or taken any drugs.

Woods told authorities he didn't know how the accident happened and that he didn't remember driving. There is "no sign of impairment" of his abilities at the time of the accident, or evidence of "inattentive driving", said investigators.

The golfer would have potentially depressed the accelerator while attempting to activate the brakes, upon loss of control of the vehicle, suggested Police Captain James Powers

The American golfer announced to be released from the hospital two weeks ago, to continue his convalescence. Twenty years after his "Tiger Slam", a Grand Slam straddling two years, Tiger Woods will not be at the Augusta Masters on Thursday, where it all began for his prodigious career now in limbo.

Tiger Woods news

From his home in Florida, between two rehabilitation sessions, after his multiple fractures to his right leg and ankle, caused by his off the road and his barrel rolls on February 23 on a road near Los Angeles, the man with 15 major coronations will surely have a heavy heart at the time of tee-time.

How to repair a bicycle wheel chain

noreply@blogger.com (sfdgd) — Mon, 22 Nov 2021 06:21:00 -0800

How to fix broken bike chain without tool

The bike wheel chain is the part responsible for moving the gears in it as required to be able to move forward when pressing on the pedals, and the chain consists of an interconnected group of screws, plates and rotating pulleys that get worn out, causing loosening or interruption over time, or their inability to move properly True.

in this article we will discuss how to fix these malfunctions.

Bike wheel track repair

Track malfunctions and ways to fix them are divided as follows:

How to fix broken bike chain without tool

Track detachment from front and rear pedals bikes (Derailleurs)

The track can be reinstalled on the gears by following these steps:

Inspect the track chain for breaks and damage to its pins, plates and pulleys, replace damaged parts before reinstalling the track, and ensure the integrity of the sprockets and gears.
Turn the bike upside down, to facilitate control and installation of the track, and avoid the bike moving.
Note the position of the front and rear gearshift levers responsible for moving the gears, as this will be the reliable place to return the track to its place; The front arch shifter adjacent to the paddles is connected to the front gears, and the rear shifter appears in the form of a metal arm under the gears located above the rear wheel.
push the rear gearshift lever forward; That is, toward the handlebar of the bike until the track chain is loose, and hold it in this position to be able to return the track to its place.
Hold the track while installing the shifter arm and place its chain on the upper side of the rear gear, then hold the other end of the track and install it on the lower side of the front gear so that the teeth of the gears are inserted into the track. A thin tool such as a pen or using the hands can be used.
Slowly moving the pedals back for one revolution, so that the gear teeth begin to fully enter the track chain, and it is recommended to rotate the pedals two or three times to ensure the stability of the track on the gears.

Hub gear split track repair

These bikes feature a box containing internal gears behind the sprockets on the rear wheel, and the chain can be reinstalled by following these steps:

Use the nut wrench to loosen the rear axle nut.
Push and hold the rear wheel to center the bike frame correctly, and re-tighten the axle nut.
Change the degree of tension and looseness of the axle nut appropriately so that the track remains on the gears.

The front and rear gears are not moving correctly

Dirt build-up in the track or a shift in the rear gear shift position is causing gear movement problems. This problem can be fixed by following these steps:

Clean the track with a degreaser cleaner, then wash it with water and add lubricant.
Tighten the nut that secures the shift wire near the rear shifter in a counterclockwise direction if the track is leaning toward the wheel links, i.e. it has trouble shifting from the small to the large gear tooth, and tighten the piece clockwise if the track is leaning away from the links, It is recommended to rotate the part gradually and move the pedals each time until the track is in the correct position.

Track chain wear and surrounding parts

The wear of the teeth of the gears, warping, and the wear of the chain causes the track to move incorrectly and affects the riding of the bike, and it is recommended to change the gears and the track chain in this case, and seek the assistance of specialists to avoid causing other problems in the bicycle.

How to know the slack of the track

It can be confirmed that the track is worn out and the need to change it by measuring the distance between every ten nails, which should be 25 cm. The track can be kept if the distance is only two millimeters, and it should be changed if the distance is more than the previous figures.

Track maintenance tips

It is recommended to follow the following things to keep the bike chain intact and able to move the gears and wheels properly:

Clean dirt and grease all parts of the bicycle drivetrain, including the track rings by the pedals, the rear wheel assembly, the rear shifter arm and the track.
Use a bio degreaser to clean the track, because it is a strong and safe detergent for the track, and medical alcohol can be used, by following the following steps:

Wet a damp cloth with medical alcohol.
Place the cloth around the track, and move the pedals so that the track turns two to three times and becomes clean.
Scrub tough grease stains intensively until they are gone.

Use a toothbrush or a bicycle brush to scrub the gear teeth using the previous cleaners, and a flat screwdriver can be used to remove dirt stuck in narrow places.
Put lubricated materials on the track after cleaning it to protect it from dirt and moisture that causes rust, by following the following steps:

Dry the track thoroughly from any moisture.
Moving the pedals to move the track, placing one drop of lubricant between every two to four joints between its joints, and not placing more than this amount.
Use a cloth to wipe the excess of oiled materials, because dirt will collect on it, and it is recommended to re-lubricate the chain if it is completely dry, or when riding the bike in rainy weather, or when cleaning the chain, or it makes a squeaking sound.

Causes of fuel injector malfunction

noreply@blogger.com (sfdgd) — Thu, 18 Nov 2021 11:26:00 -0800

Causes of fuel injector malfunction

The fuel injector is part of the fuel-to-engine delivery system. The petrol pump delivers gasoline to the injector to spray it at a certain angle and flow into the manifold, which mixes the gasoline and air in preparation for it to reach the combustion chamber to start the engine.

The failure of the sprayer causes problems in the operation of the engine, and in this article we will discuss the reasons for the failure of the fuel sprayer, the signs of problems in it, and tips to maintain it.

Causes-of-fuel-injector-malfunction

6 Reasons for a Fuel Injector Malfunction

Fuel injector malfunctions are caused by one of the following:

The low quality of car gasoline and its high percentage of impurities, which causes the fuel injector to become clogged and its inability to spray gasoline effectively due to the accumulation of dirt and particles in it.
Alkynes waxes harden around the fuel injector nozzle due to the high heat after the car has been idle or driven for a short time.
A malfunction or an electrical short in the electrical coils on the sprayer, which is responsible for creating a magnetic field that attracts the sprayer's vertical axis, so its failure causes a problem in the sprayer's work.
The inability of the crankcase forced ventilation (PVC) system to pick up oils and excess fuel during the compression process from the piston and crankshaft in its air filters, which leads to these oils reaching the atomizer and clogging it.
The presence of a crack or a fracture in the fuel injector that causes gasoline to leak from it, which affects the operation of the engine in general.
A malfunction in the control unit responsible for the combustion system (ECU) in the engine, it will not be able to direct the sprayer to pump the right amount of gasoline into the combustion chambers.

Signs of a problem with the petrol injector

The following things indicate a malfunction in the fuel injector and the need to inspect and repair it, and the following are mentioned:

Signs of a problem with the petrol injector

1. The vehicle vibrates excessively during pause

The failure of the petrol sprayer and its inability to deliver the right amount of gasoline to the engine causes the car to vibrate uncomfortably and violently during a pause, and may also result in the car being unable to move after its pause and the need to restart it.

2. Motor vibration

The inability of the injector to pump gasoline causes the engine cylinder to be unable to start the combustion process, causing the engine to vibrate significantly.

3. Engine ignition malfunction

Failure to get enough fuel into the engine due to a blockage in the fuel injector leads to its inability to ignite, and its inability to respond to increased speed when the gasoline is pressed immediately, and may also lead to the engine overheating or the air and gasoline not mixing properly, which are both They will affect the operation of the engine greatly.

4. Illuminated the check engine indicator on the dashboard

This indicator alerts you to the need to inspect the engine and the presence of a problem in one of its parts, which may be the gasoline injector.

5. Fuel Leak

Wearing the fuel injector and its stopper leads to the leakage of gasoline on its surface or on the pipes adjacent to it.

6. The smell of fuel

The fuel smell occurs when gasoline is leaking from the injector, or when it is left open without using it, and the smell may indicate that there is a leak in other parts of the car.

7. Engine idling (motor rev)

Pumping injector gas into the cylinders slows the car improperly.

8. Frequent refilling of gasoline

Injector failures cause the engine to need more fuel in a shorter time.

9. More gas emissions

Gasoline leakage from the fuel injector causes the fuel to not burn completely, which leads to more toxic gases being emitted from the car, heaviness in the air-fuel mixture and failure of the catalytic converter, which reduces the harm of these emissions by working harder.

Means to maintain the fuel injector

It is recommended to follow the following things that will protect the fuel injector from malfunctions and problems:

Periodically check the sprayer whenever the car travels between 25,000-40,000 km, to make sure it is clean and not clogged with grease and dirt, and it is recommended to check it during shorter periods if the car is not walking long distances; Because the material will be deposited more on it in this case.
Adding special materials to the sprayer in the fuel tank, which works to clean it and dissolve sedimentary materials, to facilitate its cleaning and maintenance.
Change engine oil, fuel filters, and engine; To make sure the gasoline flows smoothly without putting pressure on the fuel injector, and to avoid the injector working too hard if it is clogged or there are impurities in the oil.
Waiting for the engine to cool down before turning it off completely, to avoid the presence of heat that will cause solidification of materials on the fuel injector.

Causes of a car cooling malfunction

noreply@blogger.com (sfdgd) — Tue, 16 Nov 2021 12:18:00 -0800

Cooling system problems and solutions

The car cooling system is an important part for individuals to be able to drive their vehicles in hot weather, and the reason for the breakdown of the car’s ability to cool is due to the cooling system in it, and this system consists of hoses. pipes and other parts, and this system works to convert the coolant from the gaseous state that absorbs heat The hot car turns into a liquid state that releases heat during this process. and because all individuals care about protecting the cooling system from damage, we will present in this article the causes of the cooling system failure, and ways to fix it.

Causes of car cooling system problems

The inability of the cooling system to reduce the temperature in the car properly is due to the following reasons:

Cooling system problems and solutions

1. The accumulation of mold and dirt on the air conditioning vents

Types of bacteria grow on the air conditioner vents over time, in addition to the accumulation of dust particles in them, which will affect the exit of cold air from the air conditioner, so the vents should be cleaned every 5-6 months to avoid hot heat and disease.

2. Short circuit

The high air temperature that the car is exposed to while parking, which may exceed 45 degrees Celsius, causes damage to the internal electrical wires in the air conditioning system, and thus causes malfunctions, and it is recommended to seek help of specialists to change the damaged wires.

3. Refrigerant leak

The coolant material is the part responsible for absorbing high heat when it is in its gaseous state to get rid of it when it turns into a liquid state, so its leakage leads to the inefficiency of the cooling system, and the leak usually occurs when accidents occur, which leads to the exit of the coolant on the surface of the air conditioning hose, and then The air conditioner should be changed with the help of specialists.

4. The heat capacitor is clogged or damaged

The condenser keeps the refrigerant cool until the cold air reaches the ventilation holes to cool the car, so condensate problems affect the efficiency of the cooling system, and the cause of its damage may be the accumulation of dirt and dust in its pipes, which causes hot air to enter the air conditioner vents.

5. A malfunction in the car air conditioner compressor

The compressor (compressor) is responsible for moving the coolant material by changing the pressure to turn from a gaseous state to a liquid in the pipes, so its malfunctions cause the coolant's inability to cool the air and enter the hot air, and this malfunction usually occurs when the car is running after a long period of stopping It lasts from two to three months, especially in the winter months.

6. The combustion of the electric air conditioner valves

Valve damage leads to stopping the compressor from working, thus not cooling the air, in addition to damaging the electrical circuits, so the valves should be changed by relying on specialists as soon as they are damaged.

7. Air conditioner fan malfunctions

If the AC fan stops working, it causes a problem in spreading cold air inside the car, so it is recommended to check its ability to work every 6-8 months.

8. Compressor belt wear

Belt wear leads to the inability of the compressor to work effectively, which will affect the cooling system, and it is recommended to change it as soon as possible to avoid damage to other parts of the car.

9. Air filter clogged

Dirt and dust collect in the filter, and its blockage causes a problem with the airflow from the ventilation holes, and thus the car does not reach the desired temperature, and this problem can be fixed by opening the front dashboard, removing the filter, and changing it.

10. Engine overheating

Engine malfunctions cause an increase in its temperature, which will affect the work of the car radiator fan, which will lead to stopping the work of the compressor, and the inability of the cooling system to reduce the temperature in it as it should.

11. AC Actuator malfunction

Operating the air conditioner at maximum power and speed leads to the opening of the Air Flaps in the front of the car between the headlights, which will allow a large amount of warm outside air to enter the car and reduce the effectiveness of the cooling system in it.

12. Turn the air conditioner on and off frequently

Repeatedly opening and closing the air conditioner constantly disables the air conditioner and the compressor, so it is recommended to protect the air conditioning buttons from mischievous hands, especially in the event of children; Because they do not realize the seriousness of what they are doing.

Cooling system problems

Ways to increase the coolness of the car

An individual can increase the effectiveness of the cooling system in his car by performing some internal and external matters, as follows:

Change the air conditioner filter as soon as it becomes clogged.
Park in a shaded place to avoid heat retention in the car, and make it difficult for the air conditioner to work when it is running. It is recommended to place the car’s interior umbrellas to protect it from direct sunlight that increases its temperature and damages its parts.
Refill the coolant when its levels drop, and its level can be known with the help of specialists.
Avoid placing the air conditioner on the highest cooling setting immediately after it is turned on, but it should be placed first on the external fan setting to reduce the temperature gradually for a short time, and then put the air conditioner on the air recirculation setting, and then the air conditioner can be raised to the maximum degree of coldness.
Avoid putting the air conditioner on the medium cooling setting, which will raise the temperature in the car and not get the desired temperature. Rather, you should choose the coldest setting and change the fan speed to become the appropriate temperature.

Causes of a car horn malfunction and indications of its failure

noreply@blogger.com (sfdgd) — Sat, 13 Nov 2021 11:21:00 -0800

Causes of a car horn malfunction and indications of its failure

The horn is an important part of the car; Because it is used as an audio indicator that is easy for drivers of nearby cars to hear when they want to go to a specific place deliberately or suddenly, as its principle of work depends on the presence of buttons and switches inside the steering wheel that make a sound when pressed.

and its malfunctions cause sound problems in it that may appear in the form of the disappearance of his voice, or its issuance to a weak degree, or its issuance randomly and continuously, which may cause serious accidents.

so in this article, we will present indications of malfunctions in the horns, their causes, the way to deal with them, and their types.

Causes of a car horn malfunction

Horn failure indicators

The following things indicate that there is a problem with the horn and the need to fix it, and they are as follows:

1. Change the sound of the horn bell

A change in the pitch of the beep or a fluctuation in the volume when pressed indicates a problem with it.

2. Low beep

A malfunction of the horn or one of its parts causes its sound to be significantly reduced, and it must be replaced.

3. The horn stops working

There are many faults in the horn parts or in its electrical circuits that lead to its inability to emit a sound, so it should be inspected and repaired.

Causes of the car horn malfunctioning

A failure of one of the following parts of the horn causes problems with it:

1. Fuse valve combustion

The horn relies on electrical energy passing through the valve to produce sound, so an electrical short circuit in the valve and its combustion in the event of passing a current greater than its capacity leads to a malfunction in the horn. New valve in the same color to fix the problem.

2. Relay combustion

The relay is the electrical circuit in the horn, and its combustion leads to a sound failure, and its location can be found using the vehicle's instruction booklet to change it.

3. Contamination of the wire connection

Dirt accumulates in the connections between the wires, and this problem can be fixed by removing the dirt and reinstalling it.

4. Horn malfunction

Failure of the beep causes more current to be drawn from the valve capacity, causing it to burn out, so it must be changed to avoid burning the valve as well.

5. Faulty horn switch

It is the key that the driver presses on the steering wheel to emit a beeping sound, and it is recommended to seek the assistance of specialists to change it; Because the place next to it contains sensitive parts such as an airbag.

6. Airbag damage

The expansion of the airbag inside the steering wheel affects the work of the horn and its sound, and a problem can be found in it if its signal appears on the dashboard.

7. Wear of valve internal parts

The friction of the hot electrical wires (through which the current passes) against the valve body causes the insulation and grounding materials to wear out, which will cause the valve to burn out.

8. Clock Spring problem

It is the part located directly behind the steering wheel surface that maintains the contact of the horn wires and the airbags while the steering wheel is turning, so it should be replaced in case of a problem with it to avoid disconnecting the wires.

9. No contact of horn wires

The horn is based on two wires; One of them supplies it with power, and the other is for grounding or discharging excess power, so this problem appears when one of them breaks or disconnects, which causes an open circuit in the horn, so it must be ensured that they are connected inside it to solve this problem.

10. Ineffective contact of the horn wires

This problem occurs if the connections are loose or rusted around the horn body, which will open the electric circuit, or create high electrical resistance to any amount of electric current that passes through it, and then those connections must be changed.

Types of horns

The horns used in cars are divided into two main types as follows:

1. Pneumatic horn

They are the horns that depend on the movement of air inside their tubes, which the pump enters, to emit a sound when these tubes vibrate when air passes through them. These horns are used in old cars, but they need a programmed relay and electromagnetic wires to be responsible for controlling this system.

2. Electromagnetic horns

These horns emit their sound based on the vibration of a membrane located above their disks. These horns are divided into several types according to the design of these disks as follows:

Of the Zaomir class (Plates): This Zwamir contains several disks that may be spaced or contiguous space.
Volutes: These are characterized by a curved, spiral shape with an outward opening, characterized by their ability to emit a loud and clear sound, and their large size.
Trumpet: These are spiral-shaped horns, but their rings are longer and more elongated, and they are weaker in sound than their predecessors.

How does a car drive computer work?

noreply@blogger.com (sfdgd) — Mon, 8 Nov 2021 02:32:00 -0800

How does a car drive computer work?

Since the beginning of their manufacture, cars have relied on an automatic system that controls their parts, and this system does not aim to save fuel or reduce its damage to the environment, but rather to increase the engine speed and power, and the shift towards electronic parts industry began since the seventies of the last century, to gradually develop until it contains complex computers It controls the most accurate parts of the car, its interactions, and its various functions.

How does a car drive computer work

The function of car engine computers

The car computers that control the functions related to the engine and its operation are called several; Like the ECU/ECM, the Drivetrain Control Module (PCM), and although there is a difference in the name, they all control engine operations and monitor coordination among vehicle parts when driving conditions to change throughout the vehicle's operating life, maintaining optimum engine efficiency It is responsible for the following operations:

Regulating the fuel injection process, and controlling the injectors.
Spark plug control.
Change the vehicle's speed during idle appropriately.
Give alerts to the driver when the engine system malfunctions, by showing an illuminated message (Check engine) on the dashboard.
Monitor the ignition system.
Connecting electrical electronic commands to the transmission and camshaft systems.
Receive information from various car sensors to carry out the previous operations, such as the oxygen sensor, air pressure, temperature, throttle valve position sensor, engine knob sensor, and others to operate the engine effectively and reduce exhaust to the largest possible amount.
A simple modification of the engine functions to suit the environment in which the car is being driven, and the driver's way of driving it, thanks to its self-learning ability.

The working principle of the car engine computer

The car computer contains a large number of 32-bit/40MHz processors, which can number up to 50 processors in one car. It is worth noting that the greater the number of processors, the greater the efficiency of the car and its engine, and the processors can complete these operations using the following parts:

1. High-level digital outputs

Car computers need these outputs, which act as an electrical switch that closes and opens the circuits that control the spark plugs, the opening and closing of fuel injectors, and the engine cooling fan on and off.

2. Digital-to-analog converters

Engine parts depend on analog voltage power that controls their circuits, so digital car computers need these converters to change digital signals into analog signals.

3. Signal conditioners

It is the part responsible for converting the amount of incoming or outgoing signals to and from the sensors into an amount that fits the transformers. For example, if the transducer of the oxygen sensor can read a signal from -1 volts to -5 volts, but the signals coming from the sensor are usually between 0- and -1.1, these modifiers change it to the appropriate amount.

4. Communication chips

They are the chips responsible for applying and activating the programmed communication laws between the engine parts, the most famous of which is currently the type (controller-area networking/CAN).

Types of car computers

The car contains several types of computers that are classified into main categories that belong to them according to the function they are responsible for, as follows:

Safety Computers

Every modern car has computers that keep the car safe, such as ABS and electrical stability control, and they perform operations related to maintaining the safety of the car and passengers, such as triggering the alarm when trying to unlock the car without a key, or inflating airbags spread throughout the car's parts within a fraction of a second of hitting a solid object.

Performance Computers

These computers help in improving the performance of the car because of their effectiveness in controlling the amount of gasoline entering the engine and introducing the appropriate amount of air and other functions, which are the computers mentioned in the previous titles.

Convenience Computers

A variety of luxuries in modern cars that have become an essential part of them, which can be controlled using different computers, such as window buttons, door locks, car lighting, windshield wipers, climate, and air control systems, entertainment systems such as CD players, information displays for gasoline, speed, and others.

Diagnostic Computers

They are the computers in modern cars that perform a diagnostic function in addition to their basic function, such as recording any malfunctions in the performance of the car in the form of numbers and symbols that specialists can know; This is to facilitate the diagnosis and treatment of the problem, in addition to its ability to know the amount of exhaust emitted, engine pressure and other electrical operations in the car.

Causes of a car air regulator malfunction (air sensor)

noreply@blogger.com (sfdgd) — Sun, 7 Nov 2021 05:58:00 -0800

Causes of a car air regulator malfunction (air sensor)

The Mass Air Flow Sensor / MAF is an essential part of the engine fuel supply system. The sensor measures the characteristics of the air flowing into the engine, such as its density, temperature, and others, and sends readings to the vehicle's electrical control unit (ECU) that will supply the engine. The amount of gasoline is appropriate for the amount of air in the engine for the car to move properly, and the sensor is between the air filter and the exhaust manifold (Intake Manifold) in the front box, and it is exposed to many malfunctions that cause problems in driving the car; Because it will supply the engine with an inappropriate amount of air or gasoline, so in this article, we will discuss the causes of its damage, signs of malfunctions, in addition to its types.

Causes of a car air regulator malfunction (air sensor)

Reasons for malfunction of the air sensor

The reason for the failure of the air sensor is due to the following things:

Sensor tubes wear out over time and air flows inside them.
Pollutants, dirt, and combustion residues from other vehicles on the road build up inside, which will lead to damage.
The passage of an inappropriate amount of electricity in its wires, which will lead to the combustion of the electrical circuits in it, which are responsible for transmitting the readings to the electrical control unit.
Failure or damage to measuring parts due to shocks occurring around them, such as in traffic accidents.

Signs of a faulty air sensor

The car behaves differently than usual if the air sensor is damaged, and the difference appears as follows:

The “Check Engine” signal appears.

This light appears on the dashboard due to several things, but it may indicate a malfunction of the electrical circuits in the sensor, and it is recommended to bring a fault code reader (Error Codes) to make sure there is a problem with the sensor, as the codes will appear between (P0100-P0104) to indicate the presence of Sensor malfunction, codes (P0171/P0174) will appear if it is completely damaged.

Overclocking problem

Malfunctions of the air sensor and giving less than correct readings cause the electrical control unit to be unable to provide the engine with the sufficient amount it needs when pressing the accelerator pedal, which will lead to the vehicle not responding and not accelerating.

The car is unable to move smoothly after a pause

The car does not respond quickly after stopping temporarily at the traffic lights when the air sensor is out of order, which will affect the reduction of the amount of gasoline in the engine and the increase in the proportion of air in it.

Quickly running out of gas

Sensor malfunctions provide the engine control unit (PCM) with false readings that are higher than the truth, which will supply the engine with more gasoline than necessary, and this leads to its consumption in less time without benefit.

Black fumes come out of the car exhaust

The presence of an excessive amount of gasoline in the engine due to the wrong sensor readings leads to the wrong combustion in the engine and the production of these toxic gases, thus negatively affecting the catalytic converter responsible for treating these gases.

The inability of the car to work

The malfunction of the air sensor leads to the inability of the car to start working after stopping it completely, due to the inability of the electrical control unit (ECU) to know the readings of the air in the engine, which will impede orders for the flow of gasoline to it, and it can be known that this problem is caused by the sensor malfunction. If the engine is healthy as well as the battery and spark plugs.

The smell of unburned fuel appears around the exhaust valve

When there is an excessive amount of gasoline in the engine due to the wrong air sensor readings, this will cause this amount to leak towards the exhaust valve and the appearance of fuel smell around the vehicle.

types of air sensors

Air sensors in cars are divided into the following types:

Vane MAF

It is a sensor containing a sliding potentiometer containing several feather plates that measure readings to be sent to the engine control module (PCM), based on a change in electrical current indicating the amount of air in the engine.

Goldwire MAF

This sensor contains a thin metal plate that moves depending on the flow of air which will cause a change in the frequency of its vibration, which will be sent as readings to the Electrical Control Module (ECM).

Hotwire MAF

This sensor contains hot thin wires that regulate the amount of air flow, depending on the change in electrical resistance in them due to the passage of cold air around them, which will raise the amount of current flowing and maintain its high temperature, and this current is a signal to the engine control unit (PCM) to enter the amount The appropriate amount of gasoline to it.

Karmen Vortex MAF

The principle of operation of this sensor is similar to other sensors, but it depends on the formation of an optical vortex that is read by a photo-coupler, which connects two electrical circuits based on the light without the need to touch them, which in turn will be converted into energy that the engine control unit can read.

noreply@blogger.com (sfdgd) — Sat, 6 Nov 2021 04:35:00 -0700

Causes of a auto water pump malfunction (water pump)

The water pump is an essential part of the auto’s internal cooling system, as the auto depends on it to maintain the temperature of the auto’s interior corridor to remain complete, similar as the machine, the gasoline distributor and other corridor that heat if the pump malfunctions, which leads to damage as well. The principle of the pump’s work depends on a set of corridor, a moving shaft, rotating bus, pulleys and belts, all of which cooperate to remove the coolant from the cooling tank towards the pipes around the internal corridor to cool it.

Causes of a auto water pump malfunction

Causes of water pump malfunction

The reason for the failure of the water pump is attributed to the following effects

Not having enough coolant around the pump's mechanical seal, which will beget it to overheat, damage and leak coolant out of the pump.
The wrong use of gaskets and sealants, or their wear and gash over time, which will affect the way the pump rotates, especially the mechanical seal.
Using a coolant that isn't suitable for the vehicle’s tank or mixing further than one type of coolant, which will affect the cooling effectiveness negatively, and therefore be unfit to keep the pump corridor from high heat, which leads to damage.
The presence of contaminations, dirt and canvas remainders in the coolant material that will rub against the internal pump corridor, causing them to wear out in a shorter time.
Wearing the motor belt on the different pump gear side, or installing it inaptly, which will damage the pump in a faster time.
Shaft and bearing failures, cracks due to the high pressure caused by the pump belt being too tight.
Wear of breakers and breakers, which will affect the gyration of the pump and its incapability to distribute coolant.
The pressure in the pump system is too low, due to a blockage in the radiator or a problem in its cap, or because of a low position of fluid in the tank, or a damaged sock.

Signs of a water pump malfunction

Note the following effects indicate a problem with the water pump

Coolant leakage

The presence of a spot of coolant on the bottom after the auto stops indicates the wear of the separating accoutrements and the pump gaskets, and it's advised to consult the specialists incontinently when this problem occurs, and it's worth noting that the coolant appears in an orange, green, blue or pink color.

Dirt and rust buildup

The slow leakage of coolant leads to its accumulation on the external pump structure and its commerce with the air, causing the conformation of grease around it and the appearance of rust on it, due to the operation of a coolant that isn't suitable for the auto, or a problem in the pressure cap, which leads to air leakage outside, and the effect On the effectiveness of the coolant, it's recommended to check the corridor around the machine periodically to notice the presence of rust beforehand, and to avoid getting bigger problems.

A grassing sound when the auto is accelerating

The vehicle makes a loud noise during acceleration due to the tautness of the machine belt in the pump or its fastening gears, and the reason may be the loosening of other belts in the auto, so all belts should be checked incontinently and tensed or changed with the help of specialists when this sound occurs.

The temperature rise on the thermometer

High Auto thermometer readings indicate a problem with the intercooling system of which the water pump is part, and this means that it isn't able of effective cooling.

The appearance of bank

The appearance of bank from the frontal box of the auto indicates that the water pump is fully damaged and the interior corridor are overheated, so the auto should be stopped as soon as this is noticed, and communicate the specialists to avoid serious accidents.

Water pump results

The existent can find out the results to the problems that do in the water pump and repair them according to the needed, depending on the specialists, which are as follows.

Refilling the coolant so that the tank is filled with it before making sure the pump is running, especially when installing a new pump, and it's recommended to rotate it several times before starting the machine to insure the spread of coolant in the pump system, and to avoid dry disunion between its corridor.
Changing the old essence gaskets, and placing separating accoutrements according to the vehicle’s manufacturing instructions in a correct manner and in applicable amounts; Because the presence of a large quantum of sequestration accoutrements negatively affects the rotation position of the pump, and these accoutrements may blunder into other cooling system circuits, and it's recommended to avoid placing them in the event that there are rubber seals in the pump.
Change the pump belt and the pump if one of them is damaged; Because each pump needs its own belt.
Fully filter the coolant from the cooling system and wash it well when changing the pump, and put the applicable coolant according to the high- quality pump manufacturer, to cover the cooling system from rust.

Very dry paste.
Elastic bands, which are characterized by their heat resistance.
Self-repair strips, made of silicone with a fusible coating.

Exhaust repair methods

3 Ways to Repair the Exhaust

1. Leak repair

The heat in the exhaust pipes, and the accumulation of dirt and rust on the pipes and joints, causes holes and cracks in the exhaust, which leads to smoke leaking, and this problem is serious; The smoke can enter the car cabin instead of getting rid of it outside the car, and this situation can be dealt with by the following:

parking the vehicle on concrete or level ground away from dirt, grass, or gravel; This is to prevent the crane and the car from falling, in addition to making sure to leave the car to cool down before starting work; To avoid burning while trying to repair it.
Using a car lift to raise the car, by placing it under the car and starting to raise it, then installing special carriers under the car, to support the weight of the crane and prevent the car from falling.
Check the exhaust pipes extending from under the front of the car to the rear; To search for the location of the leak, signs of a leak can be distinguished by the presence of scratches, corrosion, or holes in the pipes, and bumps or rust can cause corrosion in the pipes, causing the leak.
Operating the car to find out the location of the leak in the event of failure to find it during the examination of the pipes, as operating the car makes it easier to know the location of the leak, and it should be noted the importance of leaving the transmission (gear) in the waiting position.
Assess the damage caused by the exhaust leakage to see how to fix it; Exhaust corroded by rust buildup needs replacing, while small holes or cracks can be treated with simple tools such as repair putty or exhaust tape, while larger holes need to use aluminum and epoxy bits to seal them.
scrub the site of damage with a steel toothbrush, then rub it with sandpaper; To remove accumulated dirt such as mud and rust, to facilitate the adhesion of tape or epoxy.
Clean the area with a piece of nail polish remover, as it strengthens the epoxy bonds on the tubes.
Exhaust tape or epoxy can be used on small holes directly, while larger holes and dents need patching, to completely seal the hole and stop the leak.
Wrap at least two layers of exhaust tape over the small holes and the area around them by several centimeters, and it is preferable to start the car after applying the exhaust tape to ensure that the leak is stopped.
Mixing epoxy and aluminum putty to fill holes or large scratches in the exhaust pipes, and placing it using a wooden piece, taking care to put it quickly, because it is a quick-drying material, as it dries within two to four hours, and the exhaust tape can be placed over the epoxy after it dries.

2. Change part of the exhaust

Part of the exhaust can be changed in the event of smoke leakage between the pipe filling and the exhaust joints, through the following:

Loosen the screws between the pipes and joints, and spray the screws with lubricating oil when there is difficulty in removing them from their place, as the accumulation of dirt on them or excessive heat can cause difficulty in removing them.
Scrape off the frayed filling completely and all around it with a scraping tool or putty knife, and secure the new filling with screws, taking care to tighten it well.

3. Install an exhaust patch

It is preferable to use an aluminum patch to fill large holes. Patches are available in auto parts stores, and they can be installed by following these steps:

Cut the aluminum can a few centimeters larger than the hole size, in the shape of a circle.
Apply epoxy to completely close the hole, then install the patch and stick it well, then apply an amount of epoxy putty and fix it with a wooden piece.
Install a larger patch over the epoxy putty along the length of the tube, then secure it with clips, taking care to seal it tight with a wrench.

Causes of a car oil cooler malfunction

noreply@blogger.com (Unknown) — Sat, 23 Oct 2021 14:22:00 -0700

Causes of a car oil cooler malfunction

The oil cooler is one of the necessary elements for the operation of the car engine, as it maintains the oil temperature at the required level, and some oil coolers use air from the outside to cool the engine system, but the oil cooler depends mainly on changing the oil into the water to feed the coolant, and it is located between The engine and the engine oil filter, and over time the oil cooler or parts of it may be damaged, which requires repair or change, so this article will explain the causes of a car oil cooler malfunction and repair it in the simplest ways and costs.

Causes of a car oil cooler malfunction

1. Oil coolant leaking

The car's cooling system contains a transformer to cool the oil, which connects the oil pipes to the radiator, and cracks or holes may occur in the seals or pipes, causing oil to leak on the ground, or lead to a leak in the oil cooler due to an internal malfunction, causing It causes the engine to overheat, reduce its lifespan or cause damage, as the oil can enter the entire engine parts as well, and the problem can be solved by asking the mechanic to help fix the malfunction in a short time.

2. Coolant leak

Coolant is an important element to maintain the temperature of the oil inside the radiator, as the fluid flows through the pipes, and if the coolant is unable to reach the radiator, it leaks out, causing the engine to overheat or damage, and a fluid leak can be observed Cooling through the presence of liquid on the ground under the car, or under the hood, or the emission of fumes from under the hood, and it is preferable to resort to a specialized person to solve this problem.

3. Mixing of coolant with oil

The function of the coolant is to control the temperature of the oil, by sending the liquid around the pipes without reaching the oil, and a defect may occur in this process, causing high pressure on the cooling system and pushing the liquid towards the radiator cap, thus leaking the liquid and mixing it with the oil, and this causes By damaging the engine, and stopping it if the problem is not addressed as soon as possible.

4. Oil pollution

The presence of a malfunction in the oil cooler gasket causes its contamination, as the oil becomes useless if it is mixed with coolant or water, and this may cause irreparable damage to the car engine, and it should be noted that the oil contamination can be observed during the change.

5. Black smoke comes out

The black smoke emitted from the exhaust of the car results from a leak of oil from the engine towards the place of fuel combustion, so it is preferable to stop the car as soon as the smoke is noticed because continuing to operate leads to significant damage to the engine parts.

6. Vibrations occur

The entry of oil into the fuel combustion chamber results in vibrations in addition to black smoke coming out of the exhaust. These vibrations occur due to damage to the oil cooler, which causes explosions in several different cylinders in the car, and significant damage to car parts when the radiator is not repaired or changed.

7. Oil cooler bulge

Swelling in the oil cooler is an important and clear indication of a malfunction or damage to the oil cooler, which may cause a break in the coolant tubes and hinder the operation of the engine, and this can be known by examining the coolant at the specialist.

8. Poor engine performance

The poor performance of the car engine is evidence of a malfunction in the oil cooler, which leads to an increase in the engine temperature, and this problem appears when the car’s acceleration is low, which means that there is a malfunction in the engine’s functions.

car oil cooler repair

The car oil cooler can be repaired by identifying and repairing the cause of the damage, or changing the coolant, and the following is a demonstration of how to repair the oil cooler:

1. Change the oil cooler gasket

The oil cooler gasket is usually made of strong materials to last for a long time, which prevents damage to the car engine, but the gasket can be damaged due to high temperature due to other problems in the engine, which leads to its damage, as the oil cooler gasket can be changed depending It depends on the type of car, and it needs a full examination to determine the extent of the damage caused by the damage to the gasket.

2. Oil cooler test

The oil cooler can be checked and tested to determine the problem and the cause of the malfunction, by immersing the oil cooler in a tank of water and compressing it with a compressed air machine to about 0.8 bar. If air bubbles appear from the oil cooler, this is an indication that it must be replaced.

Causes of the machine chain malfunction and the signs indicating that

noreply@blogger.com (Unknown) — Sat, 23 Oct 2021 14:17:00 -0700

Causes of the machine chain malfunction and the signs indicating that

The engine chain is one of the important parts to run the car engine, as it is located in the front of the engine, and it is connected to some gears and pulleys that help to operate all mechanical parts, as it operates and closes the valves at the top of the cylinder, then moving the handles that begin to rotate around The gears, the connections rotate around its teeth, and the machine chain is made of metal, so it can be subjected to wear or damage over time, and in this article, we will explain the causes of the machine chain failure, and how to fix it.

Causes of the machine chain malfunction

Several things may cause the machine chain to malfunction, and they are as follows:

The engine track teeth are damaged or eroded, and this can be known by the appearance of buzzing sounds when the car engine is running, and the loudness of these sounds when the speed is increased.
The expansion of the engine chain, and this expansion may occur due to the wear of the chain, which causes damage to the proper valves, and this can be known when the car consumes a greater amount of fuel, or the engine speed is low, or noise and crackling sounds appear inside the engine.
Slow movement or damage to the teeth, as the wear of the teeth, causes overtime to slow down the movement of the track teeth, or it may become hard, and this problem appears clearly when the engine is running and strange sounds appear.
Breaking one of the teeth of the engine chain, or breaking the entire chain, as the age of the car and the long period that it has been used can cause a break in the chain, and this can lead to significant damage to the car engine.
The engine chain is broken or damaged, and this can cause the engine light to turn on, which means that there is damage or particles inside the engine, and the presence of particles or contamination in the engine oil can cause the gears of the chain to wear out, which may cause damage to the engine or stop working.

Signs of an engine malfunction

There are several symptoms that indicate a malfunction in the timing gear chain, including the following:

Car engine malfunction

Car engines work through two methods, the first is the gear method, which is the method used in most large cars or trucks, while small cars work through the engine chain. A defect occurs in its rotation and thus leads to a defect during the operation of the engine, or a decrease in its speed.

Presence of metal particles in engine oil

It is preferable to change the engine oil when traveling approximately 3000-5000 miles in the car, as the oil begins to disintegrate when it is heated, or when it comes into contact with any solvents or particles present in the fuel, which causes the machine chain to corrode, it may be broken, and some of its particles may leak into the tank Oil, and these particles can be observed when changing the oil, so it is preferable to check the track and associated parts when changing the oil.

Engine not running

The presence of a break, damage, or loosening in the engine chain can cause the engine to not start or stop working while driving the car, as this can cause damage to the handles when they touch the valves, which also leads to the valves collapsing and thus damage the engine. Confirm this by turning to a mechanic.

Annoying sounds when the engine is running

The appearance of annoying sounds and abnormal crackling during the operation of the engine indicates a malfunction in it, as many reasons lead to the appearance of these sounds, such as a broken or loosening of the engine chain, which leads to vibration of the engine, and a slowdown in its operation, so it is necessary Checking the machine chain, it is an essential part of the engine operation process, and the engine is useless if the chain is damaged or broken.

Use of unsuitable engine oil

The use of an inappropriate type of oil for the engine can cause a problem with the engine chain, so it is preferable to choose a suitable oil for the car engine, in addition to the fact that it is necessary to contain anti-corrosion, as synthetic oils contain this substance, to prevent corrosion of the internal engine parts.

overload

Loading excessive weight in the car may cause a problem with the machine chain, as excessive loading leads to increased pressure on the car engine, which leads to chain wear and engine damage.

Oil filters damaged

Oil filters contain a valve that prevents oil leakage when the car is stopped, and when a malfunction occurs in this valve, the oil will be delayed for the engine when the car is running, which means delaying the lubrication of the engine parts, including the engine chain, so it is preferable to use high-quality filters.

Causes of car dynamo malfunction and signs of damage

noreply@blogger.com (Unknown) — Sat, 23 Oct 2021 14:10:00 -0700

Causes of car dynamo malfunction and signs of damage

The car dynamo (Alternator) is an essential and important part of supplying all parts of the car that depend on the electric current with the necessary energy.

This is in addition to permanently charging the car battery so that the car remains able to move when it is running, and if the dynamo malfunctions, it leads to a malfunction and a lack of current necessary for the car to work, so in this article we will present the reasons for the dynamo’s failure, and signs of its damage.

Causes of dynamo failure

The following things cause damage to the dynamo:

Causes of car dynamo malfunction and signs of damage

1. Damage to the IC Regulator

The integrated circuit regulator regulates the amount of electric current appropriately for the car battery without increasing or decreasing it, to keep it from burning and malfunctions, so damage to this circuit causes many problems for the battery, which will affect the movement of the car.

2. Wear carbon brushes

Carbon brushes conduct electric current to the rotating parts of the rotor inside the dynamo from the battery, but with the passage of time on them and the frequent friction of the brushes with the different parts, they will wear out and reduce their effectiveness in conducting the current, which will damage the dynamo and damage the battery as an inevitable matter.

3. Damaged or burned stator and rotor coils

The coils of these members are made of copper wires coated with insulating varnish, and they generate the magnetic field when the electric current passes through them, as the stator works to produce the electric current so that the rotating member produces the magnetic field, so the damage to their wires causes the inability of the dynamo to produce the electricity needed for the car and damage its valve The electrolyte, thus failing to charge the car battery.

4. The dynamo rollers are clogged and stop moving

Rollers contribute to making the movement of the rotor members easy and smooth, and they are installed on both ends of the rotor usually, and they are exposed over time to rust and liquids, in addition to the end of their lifespan, things that will lead to damage and affect the movement of the rotor, which will wear out the dynamo belt and damage its wires interior.

5. Bend and warp of the dynamo pulley

The pulley connects the dynamo to the engine through a belt located on it so that the dynamo begins to rotate as soon as the engine is running, and if a part of it deforms, it affects the movement of the belt negatively, or it slips and ruptures, which will lead to the dynamo stops working.

Signs of dynamo damage

The following things in the car indicate a problem with the dynamo:

1. The appearance of a light signal on the dashboard

A light signal appears in the form of a battery or the word (ALT) or the word (GEN) in English to indicate that the dynamo is unable to continuously produce enough current or produce too much current, as the amount of current it produces must be between 13-14.5 volts.

2. Car parts lighting problems

Headlights or speedometer lights dim, turn off or turn on randomly more than usual due to problems with the dynamo's production of electrical current, and lighting problems may appear as alternating flashes of high and low light, especially when vehicle parts are turned Electricity at the same time, such as using the window buttons while the air conditioner or radio is on.

3. The car stopped working because of the battery

If the battery stops working or damages it, the car is unable to start itself and turns off suddenly, and this may be caused by a problem with the dynamo, especially if it works for a short period and then turns off, so the dynamo should be repaired before it is too late and the battery is completely damaged.

4. Loosen and damaged dynamo wires

This problem appears as follows:

illumination intensity of lamps; This is due to problems in the electrical wires that conduct the current from the dynamo to the battery, which will lead to the dynamo producing a larger amount of electric current to compensate for the shortage, which will raise the heat and burn the wires.
Damage to the rectifier diode responsible for converting the alternating current produced by the dynamo into the direct current needed by the electrical parts of the vehicle.

5. Problems in the dynamo belt

The dynamo belt may derail or slip, or it may show signs of wear and tear.

6. Squeaking sounds

Squeaking sounds occur when the dynamo is damaged due to the friction of the belt with its pulley if it is bent.

7. Burning smells

Two types of burning smells are emitted when one of the parts of the dynamo is damaged, and they are as follows:

The smell of electrical burning is due to the dynamo working hard on it, or due to the burning of its internal wires in the stator or rotor.
The smell of burning rubber is due to the friction of the belt, or it may be emitted from the mucous covering the wires.

8. Problems in the operation of the electric car parts

When there are problems with the dynamo, it becomes difficult to open and close the windows using their buttons, or to turn on the radio, so it is advised to avoid using them until the malfunction is fixed, to save the energy produced by the dynamo until the specialists are reached.

noreply@blogger.com (Unknown) — Sat, 23 Oct 2021 14:03:00 -0700

Causes of the car remote control failure

A remote control device is a modern tool that allows the driver to lock and unlock the car, start the car, or activate the remote alarm.

Some control devices are attached to the car key, and some are not with the key, and both perform the same functions, even if the control device malfunctions. It causes the driver's inability to take advantage of his functions, which may affect the protection of the car and ensure that it is locked, so we will discuss in this article the reasons for the failure of the car remote control and ways to repair it.

Causes of car remote control failure

The control unit malfunctions due to one of the following problems:

Causes of the car remote control failure

1. The controller battery has expired

The controllers rely on a long-lasting lithium battery to power them, but they have a limited life, and if they run out, the controller will not be able to work.

2. Damage to the receiving or transmitting end of the controller

Control devices rely on sending signals to the car that the receiving party receives to perform its function, and if the internal wires in the device are loose or damaged, this leads to a problem at the sending end, or the problem may be at the receiving end on the car.

3. The controller is not programmed correctly

Control devices need to be programmed so that the sending end can interact correctly with the receiving end of the car, in particular, to maintain security and prevent thieves from opening it with any key. The programming problem usually occurs when buying a new car or a new control device.

4. The controller has been broken

Parts of the control device may be broken or may move from their place if the device hits a hard surface, causing it to be unable to work even if the battery and the transmitter terminal are intact, and this includes the internal parts such as the battery electrodes.

Signs of damage to the controller

The following things can be observed to check if the fault is with the controller and not any other part of the car:

The controller is unable to work properly continuously, which indicates low power in its battery, and this problem appears through the following things:

The need to press the buttons several times for the controller to respond.
The ineffectiveness of the control device when pressed within the specified area, usually up to 15 meters.

The vehicle's response to the spare controller and its ability to work better than the original, and will confirm that there is a problem with the controller's battery and not the receiver terminal on the vehicle.

The inability of the original controller to work when changing the battery to a new one, which indicates a problem with the sending end of the controller.

Controller repair methods

Controller malfunctions can be fixed by identifying the damaged part of the controller, and following one of the following solutions:

1. Restart the controller

This method is one of the simplest ways to return the remote control to its original position and solve minor problems. Follow the following steps to apply it:

Open the cover of the controller, and remove the battery from its place.
Leave the device without a battery for 15 seconds.
Replace the battery and cover, and test the controller to see if the problem is resolved.

Causes of a car coil malfunction and its signs

The car coil is one of the essential and important parts for the operation of the car. It is a compact electrical transformer that works with a current of 12 volts, and it is mostly found inside the car batteries, as it works to convert the highest voltage inside it to burn fuel and run the engine.

It should be noted that for each spark plug or what is known In spark plugs, you need a special coil connected to a handle and wires, and fixed on top of the candle, and each candle needs 15,000 or 20,000 volts of electricity to form an electric spark to burn fuel and run the engine, so the coil must be very strong so that it can perform its function, and the coil may be exposed For malfunctions that cause poor fuel intake or engine failure, and this article explains the most important causes of car coil malfunctions and the signs of those malfunctions.

Causes of car coil malfunction

There are several reasons for a car coil malfunction, including the following:

Causes of a car coil malfunction and its signs

1. Car coil overheating

The high temperature of the car coil causes a weak ability to conduct electricity, which leads to the car engine stopping or difficult to operate, and the car coil is usually made of silicon and iron, while the rest of its components and internal hinges differ, so the temperature of its internal parts is less than its temperature much.

2. Increase the electricity inside the coil

The coil is exposed to daily wear or tear, and despite its strength and durability, it will eventually begin to disintegrate and run on additional amounts of electricity during the burning process of car gasoline, which leads to damage to the insulation between the coil and the candles, and thus a mechanical failure in the car.

3. Malfunction of coil resistance

The low resistance of the coil causes a high flow of electricity through it, which leads to the damage of the entire coil quickly, as the different levels of resistance weaken the spark when ignited, which causes the inability to start the car, or stop it during work, so it is necessary to maintain Maintain a constant level of coil resistance.

Signs of a car coil malfunction

There are several signs of a car coil malfunction, the most important of which are the following:

1. Reverse Bounce

The reverse rebound of the car is one of the important indicators of the beginning of a malfunction of the car coil, and the reverse rebound occurs when the unused or burned gasoline inside the engine begins to exit from the exhaust of the car, or through the spread of black smoke from the exhaust resulting from the smell of gasoline, so it is recommended to solve the problem by Start and work on repairing the coil, to avoid the development of the malfunction and damage to the coil.

2. Low fuel consumption

Low fuel consumption is another indication that the car coil has a malfunction, and this problem can be observed when consuming a small amount of fuel while walking a long distance in the car.

3. Difficulty starting the engine

The weak coil of the car, or a malfunction in it, causes a malfunction and failure to perform the functions of the engine when the car is running, causing vibration or the appearance of loud sounds and noises, in addition to the inability to start the car. The coil malfunction can also appear while driving at high speed, The car starts to vibrate.

4. Sudden stop of the car

A weak or damaged coil of the car causes the car to stop suddenly while driving, and this occurs due to the irregularity of the ignition spark sent to the engine through the coil, which causes the engine to stop, and a problem occurs when trying to restart it.

5. Motor vibration

Engine vibration, annoying noises, or noise during acceleration are indicators of a malfunction in the vehicle's coil.

6. Engine ignition light

The ignition of the engine light on the dashboard is a clear indication of a malfunction in the car coil, as the engine light is a secondary diagnostic tool for most car malfunctions, so it is necessary to check the car coil and repair the malfunction, to avoid aggravating the problem, or damage to the coil or engine.

Tips to avoid car coil failure

There are several important tips that can be used to avoid a car coil malfunction, including the following:

Check the coil plugs regularly, as a malfunction of the plugs can cause a failure in the production of spark to ignite the fuel inside the engine, so checking the plugs helps to keep the handles healthy and good.
Inspect the coil cover and make sure that there is no fuel or oil leakage, in addition to checking the wires allocated to the electrical system inside the car. It should be noted that the first signs of a failure in the coil start from the electrical system.
Regular maintenance and checking the coil according to the attached instructions from the manufacturer, taking care to do periodic maintenance for the entire car, to make sure that there is no defect in any of its parts, in addition to making sure to resort to the mechanic when noticing any of the symptoms that indicate the coil malfunction.

The causes of the thermostat malfunction and the signs that indicate that

The heart valve inside the car regulates the temperature of the car, and controls the amount of engine coolant while the car is running;

This is to prevent the engine from overheating, but the heat valve can be exposed to a malfunction that causes the car and the engine to overheat, as it can be affected by external variables such as atmospheric changes to the environment surrounding the car, as temperatures play a major role in opening and closing the heart valve in the car, as There are several reasons and signs that indicate a heart valve malfunction, and this article will explain the most important causes and symptoms of heart valve failure.

Symptoms and causes of heat sink malfunction

The causes of the thermostat malfunction and the signs that indicate that

1. High-temperature indicator in the car

The open thermostat balances the temperature of the engine while driving. When the car starts, the thermometer indicator is on the cold side, and it begins to gradually rise up while driving, but it maintains the ideal temperature for engine operation, and when the indicator is observed to rise above the optimum temperature This is an indication that the heart valve is closed due to a malfunction of the thermostat or the water pump, which means preventing the flow of coolant to the engine, and its high temperature, and that continuing to drive the car despite the high temperature of the engine leads to damage.

2. Change the air temperature inside the car

A sudden change in the temperature inside the car indicates a malfunction in the heart valve, which may cause the engine to malfunction or impede its function, as a result of freezing coolant, or contamination of the coolant, causing delays in opening and closing the heart valve, and excessively high or low temperatures.

3. Coolant leaking

Coolant flows inside the engine while the car is running to control the temperature of the car, and any coolant leakage can lead to it accumulating around the heat valve, impeding its movement, and not allowing coolant to flow through it, and this can cause fluid to leak into other pipes.

4. Noise sounds

Swollen or damaged heart valves can cause annoying sounds and strange noises from the radiator or engine. If you do not notice any temperature fluctuations inside the car or engine, annoying noises will often appear due to a malfunction in the valve.

5. Reflection of the air conditioner inside the car

When you notice a reflection in the temperature of the air conditioning system inside the car, this is a sign of a malfunction in the heart valve. When the heating mode is turned on in the winter and the cold air continues to flow inside the car despite the high temperature of the car indicator, this means an excessive flow of coolant to the engine Due to the continuous opening of the valve of heat.

Other reasons for the malfunction of the thermostat

There are other reasons for the malfunction of the thermostat, including the following:

1. Technical problems

Poor manufacturing or any technical malfunction can obstruct the movement of the heart valve, although it is checked by the manufacturer before distributing it to the market, some technical problems may appear after use, which leads to a problem in the valve function or its malfunction.

2. Shelf life

The life span of each tool is an important part of its performance, as the life span of the thermostat is one of the reasons for its failure, due to damage to its internal parts caused by excessive cooling and heating of the regulator. This failure occurs slowly and does not appear suddenly.

3. Wrong installation

Improper installation of the thermostat can cause it to fail due to vibration while the vehicle is running and driving, causing the valve to turn upside down, stopping the coolant from flowing into the engine, as well as blocking airflow, one of the common problems that cause the valve to fail, as the flow of air towards the cooling system inside the car leads to an increase in the distance of the airflow needed to cool the engine, which means that it arrives later than the necessary time.

Heat valve repair

Fever can be repaired when any of the previous symptoms are observed by following the following steps:

Turn off the car, and allow it to cool completely, before opening the hood.
Undo the terminal cables of the car battery, install the drain cover under the car, then remove the coolant.
Inspect and follow up the upper pipeline of the coolant, to determine the location of the heart valve, and then loosen the screws fixing it, which are usually three screws.
Pull the thermostat by moving it back and forth, then clean the location of the mold with a plastic scraper, to remove any debris or rust.
installation of a new thermostat; By moving it forward and backward, then fixing it with screws, tightening it well, then installing the cables, checking the new heat lamp by running the car, and noticing any symptoms that indicate a malfunction.

6 reasons for car flash malfunctions

Causes of car flash malfunction

1. Using the wrong cable

Using the wrong or inappropriate cable can cause the flash to stop working, and to make sure of this, it is preferable to use another cable, or a flash memory to determine the location and cause of the flash failure, as the cable may not fit the model of the drive or the flash port inside the car, and therefore stops reading files It is worth noting that the appropriate type of cable can be confirmed by searching on Internet sites.

2. Software update

The type of software that the car recorder runs may not be compatible with the phone system. Therefore, it is preferable to update the software according to the make and model of the car, and the model of the car recorder on the Internet, in order to avoid facing any problems or malfunctions caused by the firmware.

3. Limited storage capacity

The small storage capacity of the flash can cause it to stop working, it is recommended to choose a drive with a capacity of 2-4 GB, to facilitate reading the flash files, making sure that the capacity matches the drive model of the car.

4. There is debris in the flash port

The flash port is one of the places most prone to the accumulation of dirt, debris and even dust, and this is due to the fact that it is an open port, so the accumulation of dirt can cause the flash to malfunction and stop working, and this can be confirmed by examining the flash port, cleaning it with a piece of soft plastic, and removing No dirt or dust inside the port.

5. There is a malfunction in the cable or port

When you notice the disconnection between the cable and the flash, this is an indication that there is a malfunction in the cable or in the flash port, and this can be confirmed by using a sharp edge as a needle, and igniting a lamp light, to notice any bends in the edges of the port or cable, or the port is loose, and it can be repaired By gently pulling the port upward to secure it correctly.

6. Drain the car battery

The flash charges cell phones by drawing power from the car battery, and this can drain all the power from the battery, causing the car to stop and charging the phone if the car model is old, and this is also a big problem for battery-powered car owners.

Tips to protect the flash from damage

There are several tips to preserve the flash from damage, and among these tips are the following:

Heat is one of the most important reasons for the car flash to malfunction, so it is preferable to avoid exposing the car recorder to a high temperature, as this causes damage to the storage cells in it, which causes the flash to malfunction.
Water is the first enemy of the car recorder, so it is preferable to take care to prevent water from reaching the flash drive, as this can cause the files stored on it to be lost, although some files may remain after drying.
Installing the car recorder inside a box of its own, in order to protect it from falling or breaking that causes damage or cracking of the flash ports, and keeping it inside a box helps protect it from the accumulation of dirt and dust inside it.
Do not leave the cable plugged into the flash port after the vehicle has been parked; The outlets can continue to draw power from the battery even though it is turned off, causing a drain on electrical power from it, so it is best to disconnect any accessories or cables connected to the car after it is turned off.

5 reasons why the gearbox malfunctions in the car

Many people are confused about the reason behind the malfunction of the gearbox in the car, and they start showing it to specialists to repair it without any knowledge of the cause of the problem, and this problem may be repeated with them over and over again without any knowledge of the reason, and in this article we will review a set of reasons that lead to the malfunction of the gearbox.

5 reasons why the gearbox malfunctions in the car

1. Lubrication

Lubrication is one of the most common causes of gearbox failure in a car. The oils used for the lubrication process form a layer that prevents engine parts from colliding with each other. There are a number of factors that affect lubrication; It is the type of oils used. If the oil is poor, it leads to the damage of the gearbox inside the car in a faster time, and therefore work must be done to choose the types of oils that are suitable for the type of car even if they are expensive, and the use of low-quality oils should be avoided; Because the cost involved will be greater. In addition, care must be taken to put the oil in the appropriate quantity; Because too little or too much of it will cause big problems.

2. Overloading

Overloading is one of the most important reasons that lead to damage to the gearbox, and the problem is that if the load is large, the problems are catastrophic, and repairing the gearbox may not be simple, but it may require a lot of cost, as the excess load puts pressure on parts The engine, and causing a lot of damage, therefore, care must be taken to take into account the load of the car or truck, and to make sure that the load in the car is proportional to its capacity, and does not cause any pressure on the engine.

3. Corrosion of the car case parts

Some parts in the trunk of the car sometimes get corroded; This is due to rust, or the accumulation of sand inside it, or the scattering of some parts resulting from the use of poor quality oil, and therefore when there is a problem in the car box, these things must be checked, and work to avoid them in the coming times.

4. Irregular arrangement of engine parts

Arranging the engine parts randomly leads to catastrophic problems, it may lead to a malfunction in the car case, or damage to the engine parts, so be careful not to tamper with the parts of the car, and present it to a competent person to avoid many problems.

5. Engine part was broken

The presence of a fracture in one of the engine parts may lead to a malfunction in the gearbox, and this fracture may occur as a result of severe pressure on the pedals, or overloading the car, so work must be avoided, and not to press the pedals to a large extent, and adhere to the required speed limits, Avoid placing an excessive load inside the car, and take into account the load that is commensurate with the car.

Signs of a gearbox problem

The car often malfunctions, but many people do not realize that the reason behind these malfunctions is a problem in the car trunk.

The car does not respond when pressing the accelerator pedal, when the car pedals are pressed, the speed must change within a second, and a delay of more than a second is not acceptable, but sometimes this delay can be acceptable if the car is running on the normal engine, And not the automatic, and the long delay indicates that there is a problem with the gearbox, whatever the type of engine.
Fluid spillage from the car. If the car is parked, and the person notices fluid spillage from it, this indicates a problem in the gearbox, and this is an easy way to identify a problem in the gearbox.
The presence of annoying sounds and vibrations coming out of the car during movement, and many people do not take this matter into account, but it indicates a problem in the car.
The presence of a burning smell, if you notice a burning smell inside the car, and this is accompanied by problems in the engine, and the inability to adjust the speed correctly, it definitely indicates a problem in the gearbox inside the car, so you must work on checking it because the burning smell may It causes catastrophic problems.

The reasons for the valves malfunction and the signs that indicate that

noreply@blogger.com (Unknown) — Sat, 23 Oct 2021 08:54:00 -0700

The reasons for the valves malfunction and the signs that indicate that

The function of the valves in car engines is to control the closure and opening of the air intake and exit valves.

They are thus responsible for providing the engine with the air needed for the fuel burning process, in addition to eliminating the air exhausts resulting from combustion.

Engines usually contain four valves; Two of them are for air intake, and the others are for exhaust, and the valves control them precisely because they affect the fuel supply process of the engine as well. Therefore, the valves malfunction cause an imbalance in the process of producing the energy needed to move the vehicle.

The reasons for the valves malfunction and the signs that indicate that

main valve parts

The valves mainly consist of the following parts, which are usually the cause of problems in the valves:

1. Camshaft

It is a long shaft that passes through the engine head, and it contains oval holes that differ in their position from each other, and the amount of air entering and leaving depends on their dimensions, and the greater their diameter, the greater the amount of air.

2. Camshaft follower/ Lifter

It is a type of bearing that is placed around the camshaft holes, to help it turn and move smoothly.

3. Push Rods

They are the rods responsible for raising the vibrating arms, and their movement depends on the vibrators, in addition to being responsible for supplying oil to the head of the combustion cylinders.

4. Rocker

They are movable levers responsible for driving the valve plug driven by the push rods or rollers depending on the type of engine.

5. Vibration bars

These are rods on which the vibrating arms are placed, and they are responsible for delivering the lubricated oil to them.

6. Fuse

The valves consist of the valve head that allows air to enter and exit the engine cylinders, as well as valve seals that hold the valve in place during its movement.

7. Valve springs

Valve springs return the camshaft and vibrating levers into place after they have moved in an upward motion, while also keeping the valve closed so the camshaft holes rotate more.

8. Timing Belt

The temporary belt moves the camshaft properly, and it consists of gears that contribute to fixing it to the valves in its inner face.

9. Belt corset

It is a type of spring that works to tighten the belt by the appropriate amount to protect it from slackening.

Causes of valve failure

Damage to the following parts causes the valves to malfunction:

1. The distance that the valves move over is increased

The valves close and open for a specific distance and quickly while the engine is running every two cycles, and are controlled by the internal parts of the valves that wear out over time, which leads to an increase in the distance they move within and causes abnormal sounds from the valves, and these problems can be solved by fixing the following things :

Adjusting the position of the rocker arms in the valves.
Change the flat shims in the valves and put new ones.
Cleaning the valve lifters when dirt and grease collect around them, especially in engines that contain pushrods.

2. Damage of hydraulic bearings

The wear of and damage to the valves causes a crackling sound from the valves, and it can be confirmed that the problem of the valves in the valves is when other parts are intact, such as vibrating arms, pressure rods or springs, with an amount of non-contaminated oils suitable for the need of the car, and this problem can be solved by applying one of the solutions next:

Adding cleaning agents dedicated to dissolving grease with engine oil to ensure the removal of materials accumulated in the cavities.
Changing the old rentals and installing new ones, and you can confirm that there is a problem with them by following the following steps:

Remove the valve cover.
Ensure that the gearshift position is switched to alignment or pause (N).
Run the engine on standby without moving the vehicle.
Put a rubber hose on the valve and listen for the sounds emanating from it, as noticeable sounds will indicate that the valves are malfunctioning.

3. Vibrating arm wear

The wear of the vibrator arm due to the lack of lubricants causes knocking sounds from the engine without affecting its functions, and this problem can be solved in one of the following ways:

Re-lubrication of the vibrator arm parts.
Change the oil filter and engine oil if it is contaminated.
Change the valve springs.

Signs of valve failure

The following problems appear in the car when the valves malfunction:

1. Blue smoke comes out of the exhaust valve

This problem occurs when oil leaks into the combustion chamber due to worn valve valves.

2. No complete combustion of the fuel in the case of pause mode

The valve face and valve seat are damaged by too much heat in the combustion chamber because the exhaust recirculation (EGR) valve is clogged with carbon residues.

3. External exhaust valve (Engine Backfire)

Damaged valve springs and problems with the engine's cylinder head cause the valve to be unable to fully close to the combustion chamber, resulting in these flames being released when the engine is running.

4. Engine rattling sound

This sound indicates problems with the spells or their incorrect location.

5. A loud crackling sound is emitted from the engine

This sound indicates wear and tear of the rocker arm in the valves.

10 Clutch malfunctions and the reasons that lead to them

noreply@blogger.com (Unknown) — Thu, 21 Oct 2021 15:16:00 -0700

10 Clutch malfunctions and the reasons that lead to them

The clutch (clutch/clutch) is an essential part in cars that have a manual transmission (regular gear), especially in old cars, as it acts as a link or separation between the engine and the wheels; So that the driver can change the gear position without turning off the engine, and its working principle depends on three main parts that carry out this process; The first is the clutch plate, the pressure plate, and the flywheel connected to the engine. They remain connected to each other thanks to the internal clutch springs when the clutch pedal is not pressed, which will allow the movement of the engine to be transferred to the wheels continuously, and they separate from each other to rotate the compressor plate and the wheel At different speeds, which allows changing gears without stopping the engine, so its malfunctions lead to the car’s inability to work and stop suddenly, and in this article, we will discuss the problems of the clutch and how to deal with it.

Clutch malfunctions and their causes

The clutch malfunctions due to problems affecting its various parts. These problems and their causes vary as follows:

10 Clutch malfunctions and the reasons that lead to them

1. Clutch slipping

This problem appears in the form of engine acceleration and deceleration of the car’s movement after pressing the gas pedal after leaving the clutch pedal. This problem appears when the materials responsible for creating the necessary friction between the clutch plates to move the movement properly and allow the gears to be changed, the cause of this problem is due to the following things:

There are problems with the clutch pedal joints, or the presence of rust around them, or they are bent and damaged, or loose or tightened too much.
Deformation or weakness of the compressor plate.
Car oil leaks into the clutch box.
The presence of fractures in the engine mounting plates.
Lubricant oil leaks from the different clutch discs, which will negatively affect the formation of the appropriate pressure.
The presence of air in the fluid transmission system of the hydraulic system wrench.

2. A squeaking sound when pressing the clutch pedal and leaving it

This sound is produced by the clutch when it is pressed when the engine is off, indicating that there is a problem with the release mechanism system of the clutch that depends on the release fork. Wires connecting or moving the switch.

3. The car vibrates when pressing the clutch

The pedal vibration refers to the incorrect and intermittent friction of the clutch plate with the flywheel. The cause of this problem is due to the following issues:

The lining between the clutch plate and the flywheel is worn out, burned, or contaminated with oils.
Warp of the compressor plate or flywheel.
A significant increase in temperature in some parts of the compressor dish.
The pilot bearing on the clutch is worn or damaged.

4. Clutch pulse

Impulsive movements appear in the clutch due to flywheel warping or a problem with the release lever and its need to adjust its position. These sudden, pulsating movements may appear after adjusting gears, which will indicate a problem in the gear shift system, and the engine is not matched correctly.

5. The pedal remains attached to the floor of the vehicle

The lack of height of the pedal after leaving it to its normal high position indicates a problem with the wire springs connecting the pedal to the internal clutch parts, or in the release bearings, so you should make sure that they are not tightened too much.

6. Loosen the clutch pedal

This problem is due to a problem with the pedal release bearings or the release fork on the clutch plate, or the presence of damage to the Diaphragm spring found in mechanical clutch types. As for the hydraulic clutch, the appearance of the problem in it may be due to one of the following things:

The presence of air in the system.
Lack of fluid needed by hydraulic clutch parts in the designated tank.
Leaking clutch hoses and connecting wires for fluids.
A problem with the valve seal on the master cylinder or leaking fluid.

7. Difficulty pressing the clutch pedal

This problem lies in the mechanism of releasing the pedal. In the mechanical clutch, the problem lies in the different parts responsible for connecting the pedal to the inner part. As for the hydraulic clutch, the problem lies in clogging or worn-out valve plugs in the clutch.

8. The sound of spinning and grinding with whistling from the clutch

This sound appears from the clutch when the gearshift is in neutral and paused (N), and the sound disappears when the pedal is not pressed and left.

9. A squeaking sound from the clutch when switching gears

This sound is caused by the clutch remaining in the active position, causing the transmission shaft to continue to rotate even when the clutch pedal is left and not pressed. This sound may indicate problems with the compressor plate or with the various release mechanism in mechanical or hydraulic systems.

10. Inability to shift gears smoothly

Clutch malfunctions lead to the driver’s inability to change gears correctly, especially in reverse gear or third gear. The reason for this problem is the need for the clutch connections to be adjusted or the clutch plate deformed, and this problem may be accompanied by a loose clutch pedal and other problems.

Tips to keep the clutch safe

It is recommended to follow the following things to extend the life of the clutch as much as possible and avoid malfunctions:

Avoid driving on potted roads daily.
Avoid driving in crowded places where the driver needs to press the clutch frequently.
Avoid pressing the pedal unnecessarily, even if only slightly.
Press the clutch pedal to get as close to the floor as possible when you need it.
Avoid pressing the pedal for an extended period at intersections.

3 reasons for the machine head to malfunction in the car

noreply@blogger.com (Unknown) — Wed, 20 Oct 2021 15:39:00 -0700

3 reasons for the machine head to malfunction in the car

The cylinder head is one of the most complex components of the car, but often these heads malfunction, and in this article, we will review the causes of these malfunctions, the signs by which it is possible to know that the engine head is broken, and how to fix these malfunctions.

3 reasons for the machine head to malfunction in the car

1. The temperature is too high

This is one of the most common reasons that lead to a malfunction in the head of the machine, as the temperature rises in the room in which the head of the machine is located, and this leads to the expansion of the minerals that make up this room, or the components of the machine head, which leads to its failure, so care must be taken to ensure that the cooling system is working inside the car, and avoid things that lead to overheating, such as thermostat malfunctions, radiator malfunctions, a malfunction in the cooling system, a malfunction in the water pump, and many other malfunctions that It may injure the car, and cause the temperature inside it to rise.

2. Valve malfunction

The valves are characterized as cylindrical pieces that are connected to the head of the machine. They regulate the combustion process by allowing the oil to enter the combustion chamber. Any malfunction of these valves affects the head of the machine; As these parts are usually iron, many people prefer to use iron valves because they are cheap and durable, but they may be damaged or wear out and need lubrication over time, so some people prefer to use bronze valves because they are self-lubricating, and they may last for several years without the need, Therefore, when the machine head fails, it must be ensured that the valves work well, and do not need lubrication.

3. The presence of a fracture or torsion in the head of the machine

The head of the machine is sometimes subjected to fracture or torsion due to severe pressure resulting from extreme temperature changes, especially since most of the machine heads are made of aluminum, and some of these heads bear torsion to a certain extent and can be returned to their place by a specialized person, and some of them are damaged and broken. We may have to change it, and this varies according to the quality of the materials that make up the head of the machine and its ability to withstand torsion, and therefore to avoid this problem, care must be taken to avoid the causes that lead to high temperature as mentioned above, and care must be taken to choose good quality machine heads so as not to They are broken or twisted and last as long as possible.

Signs of machine head damage

1. Filling the car with large quantities of fuel

When the machine head malfunctions, we may have to fill the car with more fuel than usual, and the reason for this is due to the valves being damaged. Damage to the valves leads to pumping larger amounts of fuel into the engine to provide enough power, so you should pay attention to the amount that the car needs. Usually from fuel, and if we have to fill it in unusually large quantities, we must check the valves, and make sure that they are working properly.

2. Consumption of large quantities of oils

Sometimes we notice that the car consumes large amounts of oil more than usual, and the reason for this is due to the wear of the valves, which in turn leads to damage to the head of the machine, so you must take into account the number of oils that the car needs, and an increase in this quantity indicates To the existence of a problem that must be resolved to avoid its aggravation; Because any problem can be easily solved in the beginning, but when neglected, we may have to change the parts that make up the valve completely, and this costs a lot of money.

3. White smoke comes out

White smoke is one of the most signs of problems in the head of the machine, and this smoke usually comes out of the engine and indicates oil contamination, due to a malfunction or damage to the head, or the reason for this may be the leakage of exhaust gases through the head of the machine, and that As a result of a malfunction in its component parts, and therefore when white smoke is noticed, work must be done to change the cylinder head as soon as possible, or treat it if it can be repaired; Because smoke can cause major problems if the cause is not fixed immediately.

4. Engine malfunction

The engine failure, or the inability to control it, is one of the things resulting from a defect in the head of the machine, so when you notice any problem in the engine in addition to the previous signs, the head of the machine must be repaired immediately.

Causes of car injectors malfunction

1. Pump motor failure

A malfunction in the electric motor of the car windshield sprayer pump causes the sprayers to stop working and not to spray water on the glass, due to the wear of the pump motor, or a defect in its electrical circuit, and a leak in the pump tubes can cause a malfunction in the windshield. Nebulizers, such as the separation of the pipes under the car, or cracks or fractures in the water tank.

2. Freezing water in the pump

The freezing of the water in the atomizer pump when the temperature of the place is low can cause the atomizers to malfunction, and the problem can be addressed by placing the car in a warm garage, and leaving the car for hours until the water melts, and warm water can be poured on the sides of the windshield to accelerate the melting of snow and try to run the pump to make sure the problem is resolved.

3. Clogged nebulizer nozzle

Clogged nebulizer nozzles can cause no water to escape when the pump is running. The problem can be easily resolved by cleaning the nebulizer nozzle by applying the following steps:

Lift the nebulizer cap, inspect the tubing all the way to the tank, and check where the blockage is.
Disconnect the pipes and operate the pump to make sure the water is out and there is no blockage in the pump nozzle, clean it if it is clogged with a small pin, and remove the dirt accumulated on it, or inside the pipes.

4. The power supply to the nebulizer pump is disconnected

The disconnection of the electrical current from the nebulizer pump may cause the pump to stop working, and this can be confirmed if the pump sound is not heard when the nebulizer is running, by checking the current using a voltmeter, by disconnecting the electrical wires of the pump, and checking the electrical current, as the reading appears in the number 12 It is also preferable to resort to a specialist when there is no reading, to change the nebulizer pump.

5. The tank has run out of water

The lack of water in the nebulizer pump can cause the nebulizer to stop working, and this can be confirmed by the following:

Find the tank and check the water level in it, and make sure to refill it if it is empty, or increase the water level if it is low.
Check the voltage associated with the control unit of the nebulizer, if there is voltage in the pump, and it is preferable to check the voltage between the pump connector and the control unit, as it is more susceptible to damage and corrosion.

6. Uneven water distribution

The problem of uneven water scattering from the nebulizer appears when it is operating and pulling its lever, due to blockage of pipelines or the pump nozzle, or because the pump malfunctions or reduces its operating capacity due to continuous wear when the water level is low inside it, as the water must be distributed evenly when Run the sprayer to clean the windshield of the car.

7. Cracks in pipes or tanks

The nebulizer tubes or tanks may crack or corrode over time, causing the nebulizer to malfunction and stop working. This can be confirmed by the following:

Check for any cracks or leaks in the nebulizer tubes, or the presence of a leak in the tank, by opening the car hood and fixing it well.
Locate the tank and tubes, and start the inspection from the nozzle of the tubes and tank, to the point of contact with the nebulizer, making sure that there are no cracks or holes.
Resorting to the mechanic to repair the pipes or leakage of the tank, or change it if the damage is significant.

8. Water jet damage

Damage or obstructions in the water jet can cause the water not to escape while the nebulizer is operating. This problem can be solved by soaking or changing it as follows:

Separate the tube attached to the jet from the bottom, pressing it directly and pulling it.
Detach the jet from the windshield of the vehicle using the pliers, then press and pull it up.
Soak the jet in a bowl containing a large amount of vinegar for several minutes; To clean the blockage, remove the dirt accumulated in it, then wash it with water and make sure that all the dirt accumulated inside it is removed.
Reinstall the jet correctly, turn it on to make sure the problem is resolved, or change it when needed.
