2002 Monte Carlo ss problem?
Hi, my 2002 Monte Carlo ss 3.8 has a odd sound coming from the engine specifically from the belt area, it only happens when it's idiling for more than 5 min. It sounds like a loud grinding and not a belt chirp. Belt looks like it's in fairly good shape and the alt was just tested. Could it be a pulley, hope someone can help because it's kinda getting annoying.

Anything that spins has a bearing or bushing and these can fail so a possibility is anything the belt rides on If you remove the belt, as a test, and there is no noise with a short run at idle you have narrowed it down a bit.
might be the belt tensioner, which keeps the belt tight. the bearing in this tensioner sometimes wear out. excuse the bad spelling
