I am about to replace water pump and planning to replace belts and tension pulleys but when is time to do timing chain?
How many miles before replacing timing chain? on 2003 Jeep Liberty

is it noisey right now?
no, I just thought it was like timing belts that go together with water pump.
You can usually get at least 120000miles on a timing chain or more. That is why you don't see a scheduled replacement for them. Some will last the lifetime of the engine.
