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.
Note: Replacement intervals are broad recommendations and can be affected by age, weather conditions, running conditions etc. Check with the owner's manual/ manufacturer/ dealership.
Check out the Belt Or Chain specifications for other makes and models.
