The Chevy Malibu is a mid-size sedan that was introduced in 1963. Models built in recent years come equipped with either a six-speed or a four-speed automatic transmission. The 2002 Malibu was offered with a four-speed transmission and a choice of a 2.4-liter or a 3.1-liter engine. Although the 2002 Chevy Malibu is affordable and offers solid features, it tends to experience several problems with the air conditioning.

Fan Failure

According to the CarComplaints.com website, some 2002 Chevy Malibu owners have reported problems with the air conditioning fan not working on every setting. Some drivers have complained that although the fan has five settings, it only works on the fifth setting and not the others. The fan failure mainly occurs when the heater is on rather than the air conditioning.

Recirculating Air

Owners of the 2002 Malibu has also posted reports on the CarComplaints.com website involving a number of problems with the cars recirculating air function. Some owners have reported that the recirculating air option randomly turns off and switches to fresh air.

Intermittent Shut Offs

Other 2002 Malibu owners have complained that the A/C does not work even though the A/C light is on. Some have also complained that the air conditioning suddenly shuts off after it was working and does not turn back on.

Solution

Before you pay for any repairs on your 2002 Chevy Malibu, its a good idea to have an auto shop run a diagnostic on the air conditioning unit. This should cost between $72 and $91 dollars. Fan failure and intermittent A/C problems often can be remedied by replacing the A/C control head. According to Auto Recalls for Consumers, a new control head for the 2002 Malibu costs approximately $310 for parts and labor.

The Chevrolet Silverado is one of the best selling trucks of all time. It is rugged, reliable and available with four-wheel drive. However, the front hub assembly must be serviced or replaced occasionally, due to wear and tear. When this happens, the hub nut, which connects the axle shaft to the hub assembly, must be tightened to the right torque setting. If it is not tightened enough, it will loosen and cause an unsafe condition in the front end. On the other hand, over tightening can strip the threads, leading to a costly repair. It also subjects the bearings to unnecessary heat and wear.

Clean the Parts

The underside of a car may be covered with dirt, oil, grime, snow or ice. Clean the parts thoroughly with brake cleaner or degreaser before disassembling or re-assembling any of your cars suspension components.

Determine Torque Setting

The hub nut for a 2000 Chevrolet Silverado is 155 foot-pounds, or 210 Newton-meters.

Use the Proper Tools

Always use the proper sockets, wrenches and torque wrenches. Ill-fitting sockets will strip bolt heads. Tighten the hub nut with a 35 mm socket. A dab of medium-strength thread locker, such as blue Loctite, will prevent the nut from loosening.

Test Drive

When the hub, brakes and wheels are assembled, check for looseness and excessive play. Test drive the truck and verify that the four-wheel drive and ABS systems work.

The 1995 Chevrolet Corsica depends on an oxygen sensor within the exhaust system to monitor the amount of oxygen in the exhaust. The oxygen content of the exhaust determines how much fuel the car uses to keep the engine running. If the sensor fails, your car may start to use a lot more fuel than needed. To save this needless fuel expense, buy a replacement sensor from an auto-parts store and change it at home. The location of the O2 sensor will vary, depending on the engine in your Corsica.

Instructions

1

Start the engine and allow it to warm up, heating up the exhaust system. Turn the engine off before removing the sensor. Raise the Corsica with a jack. Place a set of jack stands beneath the car to support it.

2

Locate the oxygen sensor from beneath the car. The sensor threads into the rear of the manifold or the side of the exhaust pipe. Pull the wiring harness connector apart on the end of the sensor.

3

Remove the oxygen sensor from the Corsica with an oxygen sensor socket and ratchet. Place the new sensor into the mounting area and thread it by hand until it no longer turns easily. Tighten it with an oxygen sensor socket and ratchet.

4

Torque the sensor to 30 foot-pounds with your torque wrench. Connect the wiring harness by pressing the connectors together.

5

Raise the car with a jack to remove the jack stands. Return the car to the ground.

Designed to channel fuel into the engine, intake manifolds are located under the carburetor, on the top of the engine. Chevrolet intake manifolds all look quite similar and must be identified using a series of different casting numbers stamped directly on them.

Number Location

There are two sets of numbers to be aware of: model number and the date of manufacture. Chevrolet manufactured aluminum and cast-iron manifolds, and number location differs on each. Both number sets on cast-iron manifolds are normally located near the carburetor mount. On aluminum models, only the model number appears in that location. Date codes on aluminum manifolds are stamped on the underside, making identification impossible without removal.

Number Identification

The model number code will be seven digits long. Youll have to check it against a list of Chevrolet manifold numbers, as there is no method to the numbering. GM, for General Motors, is usually stamped underneath. The date code will appear as a date, for example, 9.24.66.

Other Considerations

Many Chevrolet manifolds are interchangeable depending on horsepower and other engine specifics. Identification by using casting numbers becomes important, as manifolds may have been replaced with ones from different engines over the years. People searching for manifolds at swap meets and junkyards should have casting number erence lists for positive identification.

A fuel-injected engine uses many different sensors to determine how to make your engine run properly. The 1987 and newer GM trucks use one or more oxygen sensors located along the exhaust. Theyre not difficult to replace, but they can take some elbow grease and some basic safety equipment to do properly.

Instructions

Lift the Truck

1

First, make sure the vehicle is turned off, has cooled down for a few hours and the emergency brake is set. Using a jack, lift the front of the truck so that the front tires are off the ground. A good jack point is the front crossmember, or alternatively, the sides of the frame below the doors.

2

With the truck properly supported, slide underneath the vehicle and look for the O2 sensor. Depending on the year of the truck, there will be just one sensor located on the passenger side near the transmission, or several sensors on the later models, located both before and after the catalytic converters. Theyre easy to spot, as they stick out about 2 inches from the exhaust tubing and have two wires coming out from the body.

3

Unplug the harness that connects the O2 sensor to the stock wiring. If the clip that holds the harness together is difficult to disconnect, use a small flathead screwdriver to pop it free.

4

Using an O2 sensor socket or an appropriately sized wrench, loosen and remove the old O2 sensor. It unthreads like any other bolt would, going to the left to loosen. Should the sensor be stuck in the threads, loosen them with some WD-40 or similar product. Should the sensor still not come loose, the bung can be cut out of the exhaust, but it will have to be welded back into place by a professional, and should only be done as a last resort.

5

Before installing the replacement O2 sensor, put some anti-seize compound around the threaded area of the sensor. This will help you the next time you have to replace the sensor, as the heat of the exhaust wont cause the threads to seize up on you.

6

To reinstall, thread the O2 sensor into the bung on the exhaust, reconnect the wiring and lower the truck off of the jackstands.

Chevrolet introduced the Impala in 1958. This Impala was offered in three trims -- the entry-level LS, the mid-grade LT and the fully loaded LTZ. The LS and LT were equipped with a 3.5-liter engine, while the LTZ was fitted with a 3.9-liter engine. When searching for timing specs for a vehicle, it is important to search by the model, model year and trim rather than just the model. Timing specs change from year to year, and different trims of a model might come with different engines, as is the case with the 2010 Impala. Manufacturers began introducing computerized, distributor-less ignition systems in the 1980s and those systems are universal today. As a result, the timing is not adjustable on newer vehicles.

Firing Order

An engines firing order is the order in which the spark plugs fire to ignite a small explosion in the combustion chamber. In engines with a distributor, the firing order is determined by the order of the wires connecting the spark plugs to the distributor. In newer engines with Electronic Control Units (ECU), such as those found in the 2010 Impala, the ECU controls the firing order. The firing order for the 2010 Impala is 1-2-3-4-5-6, regardless of which V-6 engine it comes with. The firing order cannot be adjusted without replacing the ECU.

Top Dead Center

In ignition systems with distributors, the distributor can be adjusted so that all spark plugs fire when their corresponding piston is at Top Dead Center (TDC) or even slightly Before Top Dead Center (BTDC) to allow a few milliseconds for the fuel-oil mixture to ignite upon entering the pistons combustion chamber. The timing can be adjusted by turning the rotor and cap in the distributor by a few degrees. In newer cars, however, the timing is completely controlled by the ECU and the Ignition Control Unit (ICU). These are components of the on-board computer system and cannot be adjusted.

Timing Mark

On traditional combustion engines with distributors, the timing mark on the distributor pulley shows where to set the timing so that it corresponds to the manufacturers original setting. However, in vehicles with distributor-less ignitions, the mark is not adjustable. The 2010 Impala comes with a crankshaft position sensor that signals the computer system, which then adjusts the timing based on the vehicles rpm output.

The gas cap is one of the most underrated pieces of vehicle safety equipment. On one side is a large tank full of very flammable liquid, and on the other side is a world full of sparks and hot metal just waiting to set the tank on fire. Making sure your gas cap is in good working condition and sealing the gas tank correctly is one of the simplest and oft-forgotten safety checks you can make on your 2004 Chevy truck.

Instructions

1

Open the gas cap cover (the plastic piece that covers the gas cap) and remove the gas cap. Look caully at the inside of the neck leading to the gas tank and check for any deformation from overtightening.

2

Check the gas cap for any deformation of the threads from overtightening.

3

Look at the top of the gas cap for any cracks or deep scratches in the top. Turn the cap upside down and look for any damage to the O-ring. This could include breaks, cracks, thinning, discoloration or anything else that looks out of place.

4

Check the seal of the gas cap. Usually a bad seal will cause a check engine light. You can also check the seal by putting the cap on, sitting on the side of the truck bed and bouncing up and down to see whether any gas seeps out. You can also drive and look for any gas residue around the edge of the cap after you stop.

5

Watch for subtle problems with the cap. These could include high gas mileage or gas splashing down the side of the truck.

6

Replace the gas cap if you notice any signs of trouble.

Chevrolet is one the leading manufacturers of quality, American-made trucks. If you have a job to do, you want to be able to rely on the power of your truck and that it can handle the job. The Chevrolet pickup can handle most any job unless the fuel system fails. Troubleshooting the fuel system on your Chevy truck is not as tough as you might think. If you decide to tackle the troubleshooting of the fuel system, you might find the issue and fix the problem yourself.

Instructions

1

Open the hood of your truck.

2

Direct your assistant to sit in the drivers seat and be prepared to turn the key on and off when you prompt.

3

Remove the fuel line from the fuel injector unit with the screwdriver set. The fuel injector unit is located on the top of the motor. You will recognize the fuel line because you can follow it back to the gas tank.

4

Have your friend turn the key on and off quickly. If you do not see fuel coming out of the fuel line, then you need to move on to the fuel filter.

5

Follow the fuel line back from the engine compartment until you find the fuel filter located under the truck. Remove the line coming into the filter from the gas tank side with the tubing wrench set. Ask your helper to turn the key on and off again. If you have fuel flow, then you need to change the fuel filter. If you do not see fuel, then you need to replace the fuel pump in the gas tank.

The 1996 Chevrolet Lumina is a mid-size vehicle available as a four-door sedan and minivan. The Lumina was redesigned for 1995, and this second-generation design would carry over through 2001.

Battery Size

When replacing a battery, it is important to know the physical size of the battery that is needed. Most cars are designed to accommodate one specific size of battery in the engine compartment. These numerical two-digit sizes take into account the length, width and height of the battery. The 1996 Chevrolet Lumina accommodates battery size 75.

Cold-Cranking Amps

The next consideration is the cold-cranking amps of a battery --- how much "juice" it takes to get the car started on a cold day. Cold-cranking amps are the number of amperes a vehicle battery can provide for 30 seconds and maintain an effective amount of voltage per cell in 0 degree weather. The Chevrolet Lumina requires a battery with 600 cold-cranking amps. It is acceptable to purchase a battery with higher cold-cranking amps than the minimum recommendation, especially if you live in a cold climate.

Reserve Capacity

Battery shoppers can compare batteries by their advertised reserve capacity. Chevrolet does not recommend any particular reserve capacity, but it is wise to purchase a battery that offers the greatest reserve capacity within your budget.

Car engine pistons stroke up and down with the spark plug firing once for every four strokes. Each spark plug fires at a different time, providing balanced power as the engine runs. Firing order describes the sequence the pistons fire in.

Coil

The coil provides the electrical energy to make a spark. It delivers the energy to the ignition control system, which on older vehicles is a mechanical device called a distributor. Newer vehicles use advanced electronics to distribute the spark to the cylinders.

Cylinder Firing

The ignition control system delivers the spark to a cylinder at the exact moment the cylinder is ready to fire. The piston is nearly at the top of its compression stroke and the intake valve is closed. Each piston is ready to fire at a different time.

Firing Order

As the engine turns, each piston reaches the top of its compression stroke and fires in an exact order that provides the engine mechanical balance. Chevrolet 307 V-8 engines have a cylinder firing order of 1-8-4-3-6-5-7-2. The front right cylinder is cylinder No. 1. The front left cylinder is cylinder No. 2. The second cylinder on the right is cylinder No. 3 and so on.

The 2003 Chevy Trailblazer is mid-sized SUV. If your Trailblazer will not start, you could be looking at a problem with the battery or the fuel level in your SUV. When the battery charge is too low, the engine will not be able to start. The engine runs on gas so you need a sufficient fuel level to get the motor running. You can troubleshoot the problems with your Trailblazer with little knowledge of the subject before you go see a mechanic.

Instructions

1

Open the hood to your Trailblazer and locate the battery next to the engine.

2

Take a socket wrench and loosen the battery terminals. Look the battery terminals over for any corrosion. Use a wire brush and soda to get rid of the corrosion.

3

Replace the battery terminals on the battery and then try to restart the Trailblazer.

4

Use another car and a pair of jumper cables to "jump" your Trailblazer. Leave the SUV running for 5 minutes to charge the battery before cutting it off.

5

Try to restart the SUV. If the SUV does not restart, replace your battery.

6

Check the fuel level in your Trailblazer. Put gas into the gas tank and try to restart the car. Your car may have a broken fuel gauge. Adding gas will allow the car to start properly.

The Chevrolet Motor Company introduced its first vehicle to consumers in 1912. Later merged with General Motors, Chevrolet produces many wheel styles and sizes for its vehicles. Determining the wheel bolt pattern size for your vehicle will enable you to purchase the correct equipment or aftermarket replacements.

Instructions

1

Remove one of your vehicles wheel covers (if equipped) to gain access to the lug studs. Certain original factory wheel covers use faux plastic lug nut covers that secure the hub cap to the rim; you must use an appropriate size lug wrench to loosen the plastic lug nut covers in order to separate the hubcap from the rim. Certain wheel cover styles may require you to pry along the outside parameter, between the rim and hub cap, for proper removal.

2

Count the number of lug bolts that secure the wheel to the vehicle.

3

Measure the distance between the middle of one lug stud to the middle point of the stud directly across when dealing with four-, six- and eight-lug applications. For five-lug vehicles, measure from the outside edge of one stud to the middle point of the farthest stud across.

4

Note the measurement in both metric (millimeters) and American standard (inches). A wheel with five lug studs and a measurement of 4.5 inches translates as a 5-by-4.5-inch or 5-by-114.3-inch bolt pattern when converted to millimeters.

5

Reinstall the wheel cover after obtaining the correct measurements, if necessary.

The 1995 Chevy S10 is a small-sized pickup truck. If youre having problems with your Chevy S10, there are a few things that you can do before you take it to a repair shop. The most common issues do not involve invasive repair. You can attack issues with the battery, fuel or the starter head on to get your S10 back on the road as quickly as possible.

Instructions

1

Turn the ignition on the S10 to engage the electronic instrument panel. Check the instrument panel for the fuel gauge if the instrument panel turns on. If you can check the fuel gauge, make sure that there is enough gas in the fuel tank to start the car. Fill the gas tank with fuel if needed. Check the battery if the instrument panel does not turn on.

2

Pop the hood from the hood latch on the right side of the S10s grill. Raise the hood to locate the battery to the right of the engine block. The battery is in black casing with a red and black wire connected to it. Tighten the cable connections to the battery if the connections are loose. Try to restart the S10.

3

Jumpstart the vehicle with another car if needed. Connect the red (+) jumper wire to the red (+) terminal on your S10s battery. Connect the black (-) jumper wire to the black (-) terminal on your S10s battery Connect the other ends of the jumper wire to a different cars battery. Turn on the other car and then start your S10.

4

Allow the battery to charge for about 10-15 minutes before turning the S10 off. Try to restart the S10. If the S10 will not restart, you need to replace the battery. The 12-volt car battery can be found at local auto shops or department stores.

5

Climb under your S10 and locate the starter. The starter is located on the left side of the engine block. The starter is a small block box with a red wire going to the battery. Have your friend turn the ignition to the truck. Listen for a "buzz" or "click" sound coming from the starter. This indicates that the starter is faulty. Have a technician replace it.

6

Look around the S10 for any leaks. If you find leaks coming from the bottom of the S10, you will need to have a qualified technician diagnose the problem. The technician should also be the one to repair the leak as this could prove complicated and you could damage your S10 further.

You rely on the windshield wipers of your 1990 Chevrolet van to keep your field of vision clear when you are on the road in poor weather conditions. If the wipers fail and you confirm that the relay is intact, the wiper motor might be to blame. Buy a replacement wiper motor from an auto parts retailer, and change it at home.

Instructions

1

Park the van, and engage the parking brake. Raise the hood, then rest it on the support rod.

2

Use a Phillips screwdriver to remove the screws from the cowl mounted just under the wiper arms, inside the engine compartment. Lift the wiper arms up away from the windshield glass. Push the retaining clip at the base of the wiper arm, and lift it off the mounting post.

3

Remove the cowl from the engine compartment. The wiper motor is just below the cowl mounting area, beside the heater duct.

Bad wiper blades not only diminish driving visibility during a storm, but also may cause your car to fail inspection. New wipers are affordable and easy to install. Wipers are widely available from automotive parts stores or discount retailers. The toughest choice is picking a brand of wiper suited to your needs.

Instructions

1

Find the right size wiper for your Chevy S10. The wipers should be 20 inches for both driver and passenger sides of the car. However, if you want to be absolutely certain, Rain-X has an online guide to wiper sizes.

2

Visit the retailer of your choice to purchase the wipers.

3

Lift the wiper blade off the windshield.

4

Look for a button or mechanism at the center of the wiper and press it.

5

Slide the wiper blade out of the J hook of wipers arm. The blade as a whole unit should slide out.

6

Slide the new wiper blade into the J hook, until you hear the button click.

7

Tug the wiper blade gently to secure it in the J hook.

8

Remove any plastic covering from the wiper blades rubber edge.

9

Rest the new wiper blade against the windshield. Begin to reinstall the other new wiper, if necessary.

A 1969 Chevy truck might be having starting problems because of a dead battery or an insufficient level of fuel in the gas tank. The battery is one of the most important components of starting a vehicle. Without the battery, the motor will not get the electrical charge that it needs in order to start. By jump starting the battery, you can get the battery to charge up. Adding fuel to the gas tank could also be a quick fix to your starting issue.

Instructions

1

Check the fuel level in your Chevy truck. Add fuel if you think that you might have a broken gas gauge. Get a mechanic to replace your gas gauge.

2

Open the hood and attach the positive lead from your jumper cable to your battery. Connect the negative lead from your jumper cable to the negative terminal on your battery.

3

Get a friend to attach the positive and negative leads from the jumper cable to their cars battery.

4

Start your friends car and then start your Chevy truck. Leave the truck running for a about 5 minutes to allow the battery to charge.

5

Turn the truck off and then restart the truck. If the truck does not restart, you will need a new battery.

The transmission lines on your Chevy Cavalier carry transmission fluid from the cooling core in the radiator to the transmission. As the fluid heats up in the transmission, if becomes thin and less effective; cooling it becomes necessary. But if one of your Cavaliers transmission lines is leaking or damaged, youll need to replace it. Otherwise, the transmission fluid will leak or plug and the fluid level will drop, damaging the transmission. Replacement cooling lines are available, pre-bent to fit your Cavalier, from any Chevrolet dealer.

Instructions

1

Raise the front of your Cavalier off the ground, using a jack, and place a pair of jack stands under the frame to support the Cavalier. Position an oil drain pan under the radiator where the transmission lines meet the radiator.

2

Loosen the fitting on the end of one transmission line at the radiator with a wrench, then pull the line down and let any transmission fluid drip into the drain pan. Move to the other end of the line, where it meets the transmission, and place a second drain pan under the lines.

3

Loosen the fitting on the transmission end of the line youre working on, using a wrench, then pull the line out from under the car. Slide a new line in place, attaching it to the transmission first. Tighten the fitting with a wrench.

4

Raise the line to the hole on the radiator and thread the fitting in place. Tighten the fitting with a wrench until it is tight. Repeat the process for the second line. Remove the drain pans from under the car.

5

Raise the car off the jack stands with your jack, remove the jack stands and lower the car to the ground. Remove the jack from under the car.

Electrical problems in 2007, 2008 and 2009 Chevrolet trucks could result in the meltdown of "heater and washer fluid system" parts and the possibility of fire. The automobile manufacturer has issued recalls with a focus on those potential electrical malfunctions.

History

Chevrolet trucks were subject to two recalls for electrical system malfunctions---one on Aug. 27, 2008, and another on June 4, 2010. Chevrolet trucks from 2007, 2008 and 2009 for which electrical system recalls were issued are the Avalanche, Suburban, Silverado, Traverse and Tahoe.

Recalls

The August 2008 recall focused on a short circuit in the HWFS circuit board in the 2007 and 2008 Suburban, Avalanche, Tahoe and Silverado. The June 2010 recall targeted overheating of the thermal protective chamber around the HWFS fluid chamber in the 2007, 2008 and 2009 Avalanche, Suburban, Silverado, Traverse and Tahoe.

Remedies

To prevent short-circuiting, a fuse was added to the circuit control board of vehicles affected by the 2008 recall. Chevrolet agreed to disable and remove the heater and washer fluid system from vehicles affected by the 2010 recall.

Whether you need to replace a part under the hood or inside the car, you can buy a part that the company original produced or an original equipment manufacturer (OEM) part. You can find Chevrolet Silverado OEM parts in automotive retail stores. Some retailers may not keep OEM parts in stock, so you may have to place an order. Most of the Silverado parts are replaceable from engines, transmissions and cooling systems.

Removing the taillights from your 1997 Chevy S-10 pickup to replace the bulbs or complete assemblies takes just a few minutes. The taillights on the S-10 use standard 3157 dual-filament bulbs available from any auto parts store. The taillight housing also contains a 921 bulb that illuminates when you shift the truck into reverse. If the entire assembly requires replacement, salvage yards, the dealer or some auto parts stores can provide a new assembly.

Instructions

1

Open the tailgate of your S-10, and allow it to rest on the support cables. Locate the two retaining bolts on the inside edge of the tailgate opening, near the latch.

2

Remove the two retaining bolts with a 10-millimeter socket and ratchet. Set the bolts aside so you can reuse them later.

3

Grasp the taillight assembly from the rear, then pull it straight back from the bedside, removing the assembly from the truck until you can access the wiring on the back.

4

Grasp the bulb sockets, rotate them counterclockwise and remove them from the rear of the taillight assembly. Remove the taillight assembly from the truck.
