Replacing your car's air cabin filter is a relatively simple repair that can be done in a few minutes with minor tools in most cases. Always wear protective gloves and eye wear before you begin servicing your car. To replace the cabin filter, first locate the air cabin filter housing; it is usually under the dash on the passenger side or under the hood near the rear of the cowl. Air cabin filters are similar to air filters but cabin filters have better filtering qualities. To determine if your cabin filter needs to be changed, remove the filter housing retainer clips or screws and remove the filter, gently tap the filter, if you see dust falling from the air cleaner it is filled to capacity and needs to be replaced.
Step 1: Remove the main access cover, undo the cover fasteners to remove cover and side cover if needed.
Locate Air Cabin FilterStep 2: Locate and undo retainer clip to remove air cabin filter, compare the filter size to the replacement filter and reassemble. Note: clean air cabin filter housing to help keep the vehicle inlet air clean.

Replace Air Cabin Filter

Common Problems:

Air cabin filter becomes plugged not allowing air flow into the vehicle cabin.
Air cabin filter becomes moist creating mildew and odors.

Air cabin filter are a necessity for anyone needing to breath filtered air while in or driving a car. While driving there are many impurities in the air that are made airborne by passing cars. Every car in front of you is forcing the dust from the ground and into the air.
When you turn on the air conditioner or heater this air cabin filter is put into action. Like any filter it becomes dirty inhibiting the air flow through the vents. When the air cabin filter gets plugged less air can pass through until no air flow is experienced. Most automobiles have a air cabin filter easily replaceable with everyday tools. The filter is located somewhere in the heating/air conditioner duct work either under the dash or hood on the passenger side.
Replacing your car's air cabin filter is a relatively simple repair that can be done in a few minutes with minor tools in most cases. The air cabin filter can be sometimes referred as a hypo filter short for hypoallergenic filter. If you cannot locate the air cabin filter in your car please consult the car's owner's manual. Some cars are not equipped with an air cable filter so don't be alarmed if you cannot find it.
When removing the air cabin filter use caution to not allow any excess debris to enter the venting system. After the filter has been removed use a damp cloth to wipe clean the air cabin filter housing and cover. The air cabin filter will have a sealing gasket that helps trap dirt from getting around the filter. Either the filter will come with a new one or simply reuse the old one.

Black Smoke from Engine

noreply@blogger.com (Towbin Infiniti) — Fri, 04 Feb 2011 17:53:00 +0000

Black smoke is caused by too much fuel being processed inside your car's engine and then released from the tailpipe of your car. Malfunctions in fuel delivery or internal system leaks will cause black smoke to come from the tailpipe. Before fuel injection became available in automobiles in the mid 1980's, the carburetor was the main fuel and air mixer in most vehicles. A carburetor was a simple device that supplied the engine with proper fuel to air mixtures. Carburetors performed two operations 1. meter air flow 2. deliver the correct amount of fuel to air mixture. This mix could be kept even during the wide range of extra factors associated with an engine such as high temperature, cold starting, hot starting, idling and acceleration.

The primary difference between a carburetor and a fuel injection system is that the fuel injection system atomizes fuel by pushing it through a small nozzle under pressure, while a carburetor utilizes vacuum created by air flow into the intake manifold. Airflow in an injection engine is controlled by the throttle body; fuel is distributed directly in each cylinder. This creates better fuel control, lower emissions and faster acceleration. The process of measuring the amount of fuel a fuel injector is dispersing is determined by the PCM (powertrain control module). The fuel injection system has several parts: the mass airflow sensor or map sensor, throttle body, throttle position sensor, idle control valve, fuel pump, fuel pressure regulator, fuel lines, and oxygen sensors.
Cause of Black Smoke
Black smoke is caused when the mix of fuel and air becomes un-balanced. Normal mixture is 14.5 parts air to1 part fuel. When the fuel to air mixtures change because of a malfunction the mixture can go as high as 14.5 to 2 or 3, two to three times the proper amount. The black smoke is the excess fuel generated from the rich mixture and can be cause by one of the following:

Plugged Air Filter
Shorted or stuck fuel injector
Failed fuel pressure regulator
Vacuum leak
Shorted PCM Sensor

Troubleshoot Black Smoke Condition
Check Engine Light
If the check engine light is illuminated the PCM has detected a malfunction that could be causing the problem, scan the PCM to retrieve trouble codes and repair as needed.

Preventive Maintenance
To check your car's mixture you will need to use a gas analyzer to test your exhaust gases. This will measure the carbon monoxide, hydrocarbon, nitrogen oxide and oxygen content of your exhaust. During a normal smog inspection the fuel/air mixture is tested and a report generated. When a tune up is performed the spark plug end insulator can tell you whether you have a lean or rich mixture. Brownish grey is the desired color and confirms proper mixture. Black and sooty means the mixture is too rich while white to light grey confirms a lean mixture.
Fuel injection systems rely on pressurized fuel to operate. Maintaining this pressure is mandatory for the system to function properly. Replace your fuel filter with every tune up to keep your injection system operating properly.

How to Check a Car Battery

Wear protective eye wear and clothing and remove all jewelry when checking your battery and charging system. Jewelry is a good conductor of electricity and is not recommended. Most batteries wear out every 3 to 5 years and need to be replaced. Always replace your battery with an equal replacement battery to assure proper operation. Automotive batteries have a +positive terminal (red), - negative terminal (black). The battery in this illustration has a protective cover over the positive terminal to prevent short circuit in case of an accident. Electricity is stored in the battery and then supplied to the vehicle when the engine is not running. While the engine is running the vehicles alternator charges the battery for future use. (Note: never disconnect the battery while the engine is running. If the battery cable is disconnected from the battery a spark can be generated which can cause the battery to explode or a major electrical malfunction to occur.)

Checking the Battery

Test Car Battery To check a battery surface voltage, remove the positive terminal protective cover. Connect the +positive side meter lead (red) to the positive side battery terminal. Connect the - negative (black) side meter lead to the negative battery terminal. With the vehicle not running and the car sitting over night the battery voltage should be between 12.5 and 12.8 volts.

Identify Alternator

Car Alternator The alternator is rotated by a drive belt driven by the vehicles engine while it is running. Electrical voltage and amperage are generated to recharge the battery and supply voltage to the electrical system of the car. The alternator is held in place with mounting bolts. There is a main electrical wire on the rear of the alternator that supplies voltage to a main voltage junction box. If your alternator is not charging properly, your battery will slowly drain down from operating all the electrical systems in your car and stop the car from running.

Checking Alternator Output

Testing the Alternator with a Voltmeter Connect the voltage meter lead the same way you would in a battery static voltage check, Start engine (do not drive) at engine idle the voltage should be between 13.6 to 14.3 volts. If not the alternator may need replacing.
Checking Alternator Amperage Output
Testing the amperage output of the alternator is good for measuring the amount (not the level) of voltage the alternator can produce. This test can be tricky because if the alternator is weak it can still show it as producing amperage. Which is good, but if the voltage is low, it will still allow the battery to go dead. To check the amperage output of an alternator an amp meter is needed. Once the meter is connected start the engine. Next turn on all electrical accessories and raise the engine idle to about 1200 RPM. The alternator should output the max amperage it was designed to produce. Example: a 90 amp alternator should output about 88 amps. Note: An alternator cannot sustain maximum output for long periods of time. If the alternator is forced to operate at maximum output it will overheat and fail. An alternator is designed to operate at max amperage output only for a reasonable amount of time.
Common Problems:

Alternator stops producing electrical power and the car stops because the battery dies
Battery fails do to age or defect
Battery cables become loose causing the electrical system to fail

Tips to Diagnose Car Vibrations

You can identify the problem by diagnosing the vibration of the car. You can try to test-drive your vehicles. Then, you have to determine if the vibration is due to the engine, tire, drive train, or the exhaust issue. To determine this, you have to feel the vibrations of your car at the idle state. However, there are some steps you have to do to feel the vibration through the test drive so that you can make a proper diagnose.

The first thing to do is to test the front tires for a side-to-side or lateral vibrations. Do it at slow speeds and jack up each of the tire individually. Then, grab the tire on the bottom and the top and rock it. If you find any play while you move the tire out and in, you need to replace the bearings either of rear wheel drive or of the front wheel drive. Also, see whether there is a significant damage on the tire such as bulges outside or inside the tire.

Then, increase the speed of the vehicles at 45 miles per hour and see the front tires. If you feel the vibration at this speed, you have to balance the tire. You can go to the tire shop to get it done.

The next thing to do is to test the engine for the vibrations. Open the hood and then start the engine. You will need an assistant to monitor the engine. Ask him/her to stand on the side of the car and tell you what is happening, whether there is broken mounts or not. Also, put on the emergency brake. Then, place your car in drive while you press the brake medal firmly and step on the gas slightly for about two seconds but not more than 2000 RPM. If the engine lifts up or rocks, the mount is bad so that you need to replace it. By replacing the bad mount, you will be able to reduce the vibration in steering wheel.

The fourth thing you need to do is to check any possible vibration which does not affect the steering wheel. Put the transmission in neutral and then let the door open. Then, rev the engine at 3000 RPM. If you can hear the vibration in the middle of your car, you need to check the shield of the catalyst converter. It possibly gets bent or contacts body or converter.

By Melville Jackson

A car is a combination of complex machines, the working of which depends on smooth operation of its numerous parts. When any of these parts face mechanical snags, it can cause your precious vehicle to experience a number of problems. It is important to say that all mechanical problems are severe in nature and may seem quite small initially, whereas; it may grow with time. However, it is needless to say whatever the issue is; it is always recommended to repair problems with your car on time to avoid huge future repair bills. This is something which most US citizens residing in major cities like Centreville and Fairfax tend to overlook, especially since they are always busy with the fast paced life.

Most of the times when an automotive part needs to be replaced it has been noticed, that the replaced part is not as good as the original part. This has been proved by Ford Motor Company recently. Their crash tests have shown that not all replacement parts are equally created when it comes to the cost of engine repair and safety of the vehicle.

There are numerous common problems related to cars. Some of them are:

1. Warming the car: In olden days this was a good idea especially if you are planning to drive in cold weather. However, with the latest technologies that are used in modern cars, this is totally unnecessary. The vehicles which are manufactured these days come with an efficient fuel system, due to which heating up the car before driving is not required.

2. Slow gear response: It is common to see that when the gear of a car is put into reverse it takes time for the vehicle to react. Drivers often have to press the gas pedal hard to make it move. Similar is the case when the car is put in drive from reverse gear. Usually such cases mean that the transmission fluid is lower than normal. This is a common problem which most drivers in major US cities like West Springfield and Centreville experience.

Are you looking for an expert mechanic to help you with your car engine repair? Centreville and Vienna are some of the cities in US where car owners can hire expert mechanics from Advanced Automotive Inc. Apart from engine repair work they also do such services like car alignments, transmission services, and brake work.
