How to Replace a 1998 Toyota Camry 2.2L Timing Belt

How to Replace a 1998 Toyota Camry 2.2L Timing Belt

The timing belt, which transfers engine rotation from the camshaft to the oil pump, water pump and crankshaft, is the basic utility that powers all of the engine accessories. Once the belt is damaged or broken, the engine accessories aren't able to function, so the belt should be replaced at the earliest sign of abnormal wear or function. Do-it-yourself mechanics with average automotive experience can complete this task on a 1998 Toyota Camry with a 2.2-liter engine within a few hours.
