Hi All,

I made my car mad by test driving something else out of pure curiosity.

In the last day or three a whine has developed from under the hood. I've previously had the alternator rebuilt, idler and tension pulley replaced. It's definitely coming from something connected to the serpentine belt and on the passenger side of the engine.

Noise: Belt removed:
Anyone with more expertise able to ID the source or recommend tips to troubleshoot further?
