Does my 2000 Chevy cavalier have a timing belt or chain?

Your 2000 Chevy Cavalier has a timing belt. Timing belts are made of a rubber compound and are reinforced with fiberglass cords. They are used to drive the camshaft and other components of the engine. Timing belts must be replaced at regular intervals, as they can stretch or break over time, which can cause serious engine damage.
