Does my 2001 chevy prizm have a timing belt or chain?

The 2001 Chevy Prizm does come standard with a timing chain on the engine. This is a chain that goes over the timing gears in the engine and keeps the cylinders and cams in time with each other. You are fortunate to have a timing chain on the engine because it should not need to be replaced. By comparison a belt usually needs to be replaced every 60,000 to 100,000 miles and can cost over $500 to change out on a Prizm. You should still make an effort to check Your timing chain at least once a year though. You will want to make sure that it is not loose and that it is free from any debris.
