I just changed my belts with Dayco's (40410/60790). My a/c belt is fine, but my accessory belt whines. It also threw it off as well. I've checked and double checked everything for rubbing and making sure all the ribs are on the correct pullies and stuff. So I don't know what could be doing this. Any help or advice would be awesome. Thanks!

Sure it's the right size? I just replaced my belts last night, but I used the stock belts from gmpartsdirect and it's perfect. Does it seem like it has any slack in it?

Match it up to the old one & see if there the same.

They are the same. The old one was a Napa belt, but they have the same length in the part number. I'm going to just try a new Dayco belt, and if that still doesn't work, i'll just get a new GM one. The a/c belt is fine though, so I don't know.
