Timing Belt Basics

The primary purpose of the timing belt or timing chain is to maintain the timing (syncronization) between the crankshaft and the camshaft(s).

A timing belt is made of a rubber compound while a timing chain is made of chain similiar to a bicycle chain.

A timing belt wears out over time and must be replaced at the manufacturer's specified interval. Timing belt failure can result in serious engine damage.

Although a timing chain will wear over time it is usually good for the lifetime of the engine but it should be routinely inspected.
