I found that the AC tensioner pulley is starting to sqeak. I can not find just the pulley for the AC line (only sold w/tensioner). They have them for the main belt, but not for the AC belt. I asked someone at the GM parts dealer if both the tensioner pulleys were the same part and they did not know.

Does anyone here know?

I do not want to pull off the main belt's tensioner, because it has been on there awhile and scared if if i mess with it that it might start squeaking.
My next step is taking the AC tensioner pulley to the parts store for a comparison, but I don't really want to buy one there cuz they are a lot cheaper on the internet.

I would appreciate your input.

 

This should help in the mean time. When you have the pulley off, you can see what bearing is actually in there. If its squealing, it should be replaced, but this link will help in the mean time.

Thanks for the link. Its at least worth a try and wouldn't hurt.
