How to Replace a Car Timing Belt

Replacing the timing belt on your car, though not easy, can be done in your driveway. Replacing the timing belt is more complicated than replacing a fan belt and involves much more work. When changing the timing belt, it is a good idea to replace the water pump also since it has to be removed in the process. Learn how to replace a car timing belt by following these steps.

Instructions

1. Disconnect the battery and remove the distributor cap. If your car doesn't have a distributor, make sure the cam position sensor is at "Top Dead Center" (TDC). Consult a repair manual made for your specific vehicle to determine this.

2. Rotate the engine so the timing mark on the crankshaft pulley is in line with the "0" mark on the timing scale. Rotate the engine until the distributor rotor is aligned with the index mark on the distributor housing.

3. Remove bolts, screws, other belts and parts that interfere with the removal of the timing belt. Each model is different and has different parts in the way of the timing belt. Consult a manual for specific parts and removal instructions.

4. Loosen the timing belt tensioner and mounting bolts but do not remove them. Move the tensioner away from the belt and then tighten the mounting bolts to hold the tensioner in place.

5. Slide the timing belt off and remove it from the engine. It should easily slide off after the tensioner is loosened.

6. Replace the timing belt with a new one and reverse the removal steps. Read the engine manual to know how hard to torque the tensioner bolts and other bolts when replacing parts. Keep the marks on the pulleys aligned at all times.
