High Pitch Squeal

I've found that many people have asked about it, but nobody has gotten an answer. During moderate to hard acceleration there is a very loud squeal coming from my engine compartment - belt was replaced recently and its still there. It seemed to be reduced for about an hour after I got my car back then returned right back to being as loud as ever.

Some people have cited the tensioner or some sort of PVC leak causing the noise, and I just want to see if anyone out there has any clue the source of this noise. Pretty disappointing because this is a great car otherwise.

I Agree!

I have this problem too with my 2008 Pontiac G6 Convertable and it's driving me nuts!!!:mad:

It was happening on a regular basis - But now, it is on and off - I read some of the other posts and they all sound like mine - I hope that it can be fixed.
