If so how much did the labor cost and how long will it take to have it replaced im pretty sure i need mine changed soon noise is coming from the engine in the timing chain area I have a 2002 grand am 2.2 ecotec with 95000 miles on it

Have a mechanic diagnose the sound first. 95K is very low miles for a timing chain problem. Even if it is in that area, it may not be the chain causing the noise, so a new one won't fix it. If you havn't already, remove the serpentine belt and see if the noise goes away.

Can't help with time/cost... most ecotecs aren't in need of a timing chain yet.

It is too soon for a timing chain replacement, but worn timing chain guides will start to make a little noise in these engines. This noise is harmless, but annoying. I had my chain replaced for this same type of noise, the mechanic said that the chain and the tensioner were both good, but the guides were worn to a point that a noise could be heard. I only had the chain and tensioner replaced because everything was all taken apart. It cost $750.00 so it is a good idea to wait on this one.

well I hope you guys are right id hate to be driving and have ny timing chain break. well thanks for the info I just thought the timing chain wear was accellerated in my car due to me lending my car to my sis and it over heating on her

I've got almost 190,000 miles on my 2.4l, I don't think yours will break at 95,000

How bad did it overheat? It's possible there's internal engine damage.
