I just owned a 95 saab 9000CS and the owner's manual doesno
t mention any thing about maintenance of timing belt/chain. Just tells the drive belt should be replaced at around every 100,000km. What is the difference between drive belt and timing chain or they are just the same thing? where are they?

Thanks a lot!

On the 9000 the belt drives the water pump, alternator, steering pump etc while the timing chain drives the camshafts. If the former snaps then it is not serious. If the latter does then big trouble! The belt is cheap and easy to renew. The chain is expensive and difficult to replace.
