Idler Pulley

smokedbystang · Jan 18, 2017

I have a whine coming from the engine when accelerating/decelerating and I believe it is the idler pulley near the alternator. From reading on here lokks like an easy fix. I searched online and on here but could not find the answer. Are both idler pullies the same size? The one near the alternator and the one on the tensioner. I only see one listed on advance auto website and just want to make sure. Maybe the one on the tensioner comes as one piece. Thanks.

How many miles are on your 12? My 11 has 86000 miles and I just ordered all of it from RockAuto for about $65 includes police belt and the tensioner. Might as well do it all at the same time.

Looks like the tensioner comes with a pulley so I think I answered my own question. The tensioner, pulley and belt are about $85 at advance auto. If I spend another $15 I can get 40% off so I usually get all my parts there. Usually much cheaper with the discount. Thanks for the info.

Ended up getting a new belt and idler pulley and good as new. Noise is gone.
