Hey guys,
I've been working on figuring out a resolution to a belt squeak/chirp I'm getting on my 2009 Vibe base 1.8L Auto with 165K miles. I get a consistent chirping from my serpentine belt area. As many of you know there are 4 pulleys on the '09 1.8L (Alternator, water pump, A/C Compressor, and Crankshaft pulley).
Here is what I have done:
Adjusted the belt to be a little looser, no change
Adjusted the belt to be a little tighter, no change
Replaced the belt with a new Continental belt, no change
Removed alternator and had it tested at Autozone (more to isolate the pulley on their machine than test the actual function of the alternator), no chirping coming from it.
Replaced the water pump under warranty from when it failed 4 years ago, no change
Test spun the pulleys by hand (except CS) and all move fine without noise.
So I'm down to either the A/C compressor or crankshaft pulley causing the noise I believe. The crankshaft pulley does look to have an ever so slight wobble to it, but its hard to tell, it could be my brain trying to place the blame on it .
What suggestions or help can you guys offer? Any experience with this?
Here is my car:
