Mercedes c200 cdi hasn't got timing belt. Has got chain.
It doesn't have a timing belt...it has a metal timing chain...these do not standardly wear out for a very long time.
the 2001 does not have a timing belt,instead a timing chain,which does not required replacement as often as belt
It should last as long as the engine.
If the engine has a timing belt, it should be changed around the 150K mark. If there is a timing chain, it does not have to be changed unless it is damaged.
Unless there is something wrong with it (there shouldn't be), you should never have to replace the timing chain. That's the beauty of chevy.
Unless a timing chain is making a noise or has jumped a tooth, they need not be replaced. Timing belts need changing according to the specs spelled out in the owner's manual.
I looked for an answer to this question in my Haynes manual and found nothing about how often to change the timing chain. It DOES, however, to into great detail about how to do it. FriPilot simply because they dont have a timing chain on the 2.2 ecotech
Timing chains are designed to last the life of the engine.
There is no timing belt. It is a chain driven cam and there is no change interval. They get changed when the engine is overhauled.
It does not need to be changed unless it fails.
When you here a rattling noise from the engine at idle.
