A faulty thermostat can cause a number of problems, such as engine overheating and reduced cooling system efficiency. Although the thermostat is a small, inexpensive component, its absolutely critical to the proper operation of a liquid-cooled engine. The 3.0-liter engine in a 2001 Toyota Avalon contains a thermostat thats designed to open at a temperature of 176 to 183 degrees Fahrenheit. The most common thermostat fault is a failure to open. In this situation, the thermostat valve doesnt open when it should, preventing coolant from properly circulating and causing the engine to overheat.

Instructions

Removal

1

Allow the engine to cool for at least two hours to prevent burns and other injuries related to the high temperate of the engine and engine coolant.

2

Raise the vehicle with a jack and support it with jack stands. Remove the radiator cap and place a drain pan underneath the radiator. Loosen the drain valve with a ratchet and metric socket. Allow the coolant to drain out until the stream flowing from the radiator slows to a drip. This may take 30 minutes or more. Close the radiator drain valve. Place the drain pan under the engine, beneath the thermostat housing.

3

Remove the bolts holding the V-bank cover in place at the top of the engine with a 5 mm hex wrench. Remove the bolts holding the air cleaner hose and resonator in place with a ratchet and metric socket. Then remove the air cleaner assembly from the vehicle.

Turn the ignition on for 2 seconds and off for 10 seconds to pressurize the fuel system. Start the engine, and check for fuel leaks.

A catalytic converter in a car helps eliminate harmful exhaust emissions that contribute to air pollution. After many years of use, the converter can become clogged and cause the vehicle to run poorly. Usually, the car will have very little power and will not be able to achieve a speed above 20 miles per hour. These are the two main symptoms that a new catalytic converter may be needed.

Instructions

1

Locate the catalytic converter by tracking the exhaust pipe from the engine: the catalytic converter will be the first large rectangular-shaped object that you come across. It looks somewhat like the muffler, but it will always come first in the exhaust system before the muffler. Raise the front corner of the car on the side that the catalytic converter is nearest to with a jack. Slide a jack stand under the frame of the car and lower it onto the stand with the jack. Crawl under the vehicle and spray penetrating lubricant onto all of the bolts on the exhaust system near the catalytic converter.

2

Use a wrench to unscrew the oxygen sensor that connects to the exhaust system near the catalytic converter. This sensor will be a small piece sticking out about the size of a spark plug. There will be a wire attached to it. Allow the sensor to hang off to the side by this wire.

3

Loosen the bolts in the clamp between the catalytic converter and the engine with a wrench then remove the clamp. Move to the back of the converter and locate the bolts in the coupling in the exhaust pipe. Use the wrench to remove these bolts. The catalytic converter and the pipe attached to it will drop down slightly.

4

Work the assembly back and forth to pull the pipe apart where it was clamped in front of the converter. You will also be pulling out the pins attached to the exhaust pipe that go through the rubber bushings on the exhaust pipe hangers. When all of this comes loose, you will be able to pull the converter out from under the vehicle.

5

Slide the new converter under the vehicle. Lift it and slide the pipe on the front of it onto the exhaust coming from the engine. At the same time, push the pins into the bushings on the hangers. When the catalytic converter is properly positioned, the rear coupling should be ready for the bolts to be reinserted and tightened. Use the wrench and tighten these bolts.

6

Move the clamp back into position in front of the converter and tighten the bolts to fasten the pipes securely. Screw the oxygen sensor back into the port on the exhaust pipe and tighten it with the wrench. Start the car and check for leaks. Tighten the bolts if any leaking is present. Remove the jack stand and lower the jack to return the car to the ground.

The Ford Contour was a compact four-door sedan that Ford manufactured from 1995 to 2000. Ford also sold the Contour as the Mercury Mystique, and marketed this vehicle as a replacement for the Ford Tempo and Mercury Topaz. The Ford Contour had a 4-cylinder 2.0L engine or a 6-cylinder 2.5L engine. Both of these engines had multi-port fuel injection, which requires a high-pressure fuel pump. The fuel pump in the Ford Contour is accessible from the rear seat.

Instructions

1

Detach the cable from the batterys negative terminal. Open the filler cap for the fuel tank, and disconnect the air cleaner. Connect a fuel pressure gauge to the pressure relief valve on the fuel rail, and place the end of the drain tube into a container. Open the fuel pressure gauge, and allow the fuel to drain into the container. Remove the fuel pressure gauge, and close the filler cap to the fuel tank. Connect the air cleaner assembly.

2

Remove the cushion from the rear seat, and disconnect the grommet on the floor pan. Detach the electrical harness from the fuel pump. Press the tabs on both sides of the quick-connect fittings for the fuel lines of the fuel pump, and gently disconnect the fuel lines.

3

Turn the locking ring for the fuel pump counterclockwise with Fuel Tank Sender Wrench D84P-9275-A. Detach the locking ring from the fuel pump, and remove the fuel pump without damaging the fuel gauge sender or fuel filter.

4

Discard the O-ring on the fuel tank, and clean the groove on the fuel tank with a shop rag. Apply a thin layer of grease to the new O-ring seal, and place it onto the groove of the fuel tank. Carefully install the fuel pump into the tank to prevent damage to the fuel gauge sender or the fuel pick-up filter.

5

Place the locking ring for the fuel pump so that the locking tabs of the locking ring are under the locking ring tabs of the fuel tank. Turn the locking ring clockwise with the fuel tank sender wrench until the retainer ring is against its stops. Connect the fuel lines and electrical connector for the fuel pump. Connect the grommet on the floor pan, and replace the rear seat cushion. Connect the cable for the negative battery terminal. Start the engine, and check for fuel leaks.

An accident can leave your vehicle without a functioning side mirror. It is simple to replace a side mirror, but whether you buy a new replacement mirror or a used one, the mirror probably will not match the paint color of your car. A few coats of paint can transform the replacement mirror and make it look as if it was the original.

Instructions

1

Locate the factory paint color code for your car. This is the key to getting the best color match for your replacement mirror. Check the records for your car or contact your local dealer to find the code. Buy the paint and primer from an auto parts store.

2

Lightly sand the plastic on the replacement side mirror with fine-grit sandpaper. Wipe away the sanding dust from the mirror with a damp cloth.

3

Tape off any areas of the replacement mirror you do not want painted, using painters tape. Set the replacement mirror on a drop cloth in a well-ventilated area.

4

Spray the mirror with aerosol automotive primer. Apply the primer in two light coats. Let each coat dry before handling or applying paint or primer.

5

Spray the mirror with aerosol automotive paint. Again, apply the paint in light coats. Apply three coats of the paint, letting each coat dry before applying the next. Give the mirror 24 hours to dry before handling it. Remove the painters tape.
