This eng. has a chain, replace it when you HEAR it!!! It should go 150,000 or more.
If you hear a metallic rattle (especially on cold start up) or any time engine is running
then it is time to replace the timing componets! Leave the music off any time you start any engine
and listen, it can save some $ one day. But nobody does that right cause it takes all of about 10 seconds.
good answer wetry I wasnt sure if it had a chain or belt I liked the comment about the music
Thanks, i was not sure either. I looked it up. But the answer is pretty much the same on all chain
equipped engines. I thought GM 2.4's had a chain. A engine can tell you a lot if you just listen.
