Just wanted to let you guys know with winter and cold temps those idler pulleys start to squeal... Here is a good link

looks like they figured it out - I see $27.99

Are the A/C idler and the crank idler the same part or are they different?

geerookie

they are different.

Would the diffrerence in price be due to the fact that you only get the pulley? I was thinking that you got the spacers(?) and dust sheilds(?) when you ordered the GM piece. If anyone knows chime in. I'm needing one now too.

Rockauto.com has pulleys only for under $13, and the Gates one is steel. Haven't tried it so I don't know if it is any better.

Glad to see this post as I think I am now having this problem. Have 2 vettes but never heard this sound before. Gets faster with acceleration; no problem in performance.

Naive question: is this a signal for an imminent failure or an annoyance that can be addressed after driving 40 miles?

Thanks!

GM parts (pulley) come with spacer, dust shield and new bolt. PARTS of America sent the Factory Air Idler Pulley, which is NOT the a/c idler pulley.. They do not carry an a/c idler pulley.. Factory Air is a Brand Name.. Is that messed up or what?

go direct to GM, www.gmpartshouse.com

the a/c pulleys(2 of them, 1 on the tensioner), are identical, they run about $30 shipped

then you have a the main belt tensioner, $50 and the idler puller below the p/s pump, $20
