Intermittent High Pitch Shrill
#16
Right Jim, I recall your prior post on that when you replaced it. Since then, I've seen pulleys without tensioners. Just wondered if you had isolated the problem to one or the other. But as you point out, it's best to replace both as an assembly.

Worn or loose serpentine belt will produce squealing sound and the sound will vary depending upon the engine's RPM. If Boca's observation that the noise doesn't vary with engine's RPM is correct, then he can pretty much rule out the source of the noise is coming from rotating bodies driven by the engine.
