Change A Timing Belt

Changing a timing belt requires a conversant licensed, as the complication ratings on timing belts are for "A" or "B" mechanics. Besides, timing zone replacement procedures are contradistinct for all vehicles, nevertheless many of the steps are in agreement.


1. Alter the belts on cars that accomplish not accept interference motors. Provided your vehivle does chalk up this Engine, accede other matters that may acquire broken when the timing belt broke or extended. Your motorcar generally has an interference Engine whether it has added than two valves per cylinder or has double-overhead cams. On interference motors, the valves may be hitting the pistons and doing more damage. You may hold to alternate the top edge of the engine or the full engine whether you annex internal damage. You can't tell whether you have bent a valve or if the motor has sustained other internal damage without replacing the timing belt.

2. Jack up the car to get to the bottom bolts. Once the timing cover is off, check if the engine is set at top dead center (see Resources below).4. Jack up the engine and remove the motor mount. Using the tensioner, loosen and remove the belt.

To replace timing belts on most cars, unhook the positive battery cable and place it aside, away from the car. Remove all accessories, such as the alternator, air conditioning compressor, power steering pump and other accessories that may hinder your access to the timing belt cover.3. Remove the belt cover, which may be in one piece or two.

Check whether the problem was in the tensioner. Replace the belt and the tensioner, if needed. When you replace the belt, be sure that the marks on the cam (or both cams, if you have a double-overhead cam) and the crankshaft marks are in place. Check that the tension on the belt is on the side opposite the tensioner.

5. Replace the motor mount. Once the belt is on, using a large ratchet and socket, turn the engine over at least twice to be sure the valves are not hitting the pistons. This step must be performed by hand. Do not use an air ratchet and do not turn the car over by "bumping" the engine with the starter.
