I have replaced the pulley... but not the tensioner bracket because it is hard to pull...spring has a lot of tension
Hi I would next check the one way pulley on the alternator as these have been known to seize up and cause horrible noises on the drive belts. To test it you need to remove the belt and the grab the pulley in one hand and spin it back and forth quite hard. One way the alternator should also turn internally and the other way the alternators internals should stop due to the one way clutch inside the pulley unit. If that is of check the bottom pulley as the rubber bonding between the 2 sections can break lose allowing the outer section to slip on the inner section.
I hope this helps further and please feel free to ask if I can help you further
With the serpentine belt off..... it is squealing TERRIBLY.....
Alternator is ok... All accessories are ok... the noise is coming from behind the timing cover
I have removed the timing cover on the top ... it is a chain ...not a belt..??? so now....what could be squealing like we have previously talked about
Is it possible that the turbo would be making the squealing noise because with the belt off of the car.. it squeals but it doesnt squeal "under a load" (acceleration)
I had a another mechanic listen to this noise ... He poured water on the crank pulley and the noise stopped... So ... I assumed it is either the seal or the crank pulley. I have removed the crank pulley and my question is: Is the crank suppossed to move( wobble) or is it suppossed to be stationary......
