Stock Cars Review

1. Remove the two bolts that secure the water outlet housing to the Audis engine with a socket and ratchet. With the bolts removed, lift the housing off the engine to expose the thermostat.
2. Note the positioning of the thermostat inside the engine. When you replace the thermostat, you must install it with the same positioning. Pull the old thermostat out of the engine and plug the hole with a shop rag.
3. Remove the old gasket from the engine with a wire brush or metal scraper. Do the same for the old gasket material stuck to the bottom of the water outlet housing.
4. Pull out the shop rag from the engine and install the new thermostat into position. Place a new gasket over the thermostat.
5. Place the water outlet housing onto the gasket and secure both to the engine with the socket and ratchet.

Fuel Pump Replacement
1. Before attempting to remove the old fuel pump, disconnect the negative battery cable using a 12-mm socket. Place a block under the front wheels to prevent rolling. Locate the electric fuel pump under the rear floor panel. Jack up the left rear of the car and support it on a jack stand. This will provide plenty of room for you to remove the fuel pump.
2. Remember that gas is highly flammable, so keep a fire extinguisher nearby. Using a Phillips screwdriver, remove the intake and outlet hoses from the fuel pump. Use bolts to plug up the inlet and outlet hoses to prevent gas from leaking.
3. Using an 8-mm socket, disconnect the negative and positive wires from the fuel pump. Unbolt and remove the fuel pump and vibration pads with a 14-mm socket. Compare the old fuel pump to the new one to ensure that you are installing the correct replacement part.
4. Install the new fuel pump. Secure it to the Mercedes-Benz 450SL using the 14-mm socket. Connect the brown negative wire to the negative brown terminal and the positive red/black wire to the red positive terminal on the fuel pump. Using the Phillips screwdriver, connect the inlet and outlet hoses to the fuel pump. If a secure connection cannot be made, you may need to replace the hose clamps.
5. Remove the jack stand and lower the vehicle to the ground. Reconnect the negative battery cable and start the car. Check under the rear floor panel for fuel leaks.

1. Loosen the lugs on the wheels using a 1/2-inch ratchet wrench and lug socket. Place wheel blocks on the opposite end of the vehicle being lifted. Position a hydraulic lift under a structural body point and lift the vehicle. Use a pair of jack stands to secure the vehicle on each side, placing them under structure points.
2. Remove the lugs and place inside the wheel. Slide the wheel under the vehicle as close to the work area as possible for extra security. Remove the four retainer bolts holding the caliper to the wheel assembly using the Allen wrench set. Gently tap the caliper with the rubber mallet to remove from the rotor.
3. Use the C-clamp to push the caliper piston to its full open position while the original brake pads are still installed. Remove the original brake pads by prying the clips off the caliper unit with a screwdriver. Install the new brake pads by fitting them into place and prying the clip onto the indented spots of the caliper.
4. Place the caliper back into position over the rotor. Tighten each retention bolt to the specified torque. Reinstall the wheel and hand tighten the lugs. Remove the jack stands and lower the vehicle. Use the 1/2-inch ratchet wrench and lug socket to ensure each lug is tightened to the recommended torque. Enter the vehicle and press the brake pedal until it becomes stiff. Repeat for each wheel.

3. Gently twist the screwdriver to lift the door. If that doesnt work, use the screwdriver to gently pry off the door.
4. Use the Phillips screwdriver to remove the two screws located under the door that covers the battery.
5. Separate the two pieces of the key and remove the battery cover to access the battery.
6. Use the small, flat-head screwdriver to lift the battery out, if required.
