Cold start belt squeak

[whiteTy1214]

I am having a cold start belt squeak issue. I have changed the belt, tensioner, idler pulley, new a/c comp. It does not squeak when warm. Any ideas to fix this would be great.
Its driving me crazy. thanks again

Re: Cold start belt squeak

thanks for your reply. I have flipped the belt before and got no noise.
after awhile the noise would return. So i bought a new belt with tensioner. noise gone.
now its back. Thinking misalignment, reading your link thanks for the great info.

Update...
I got a new drive belt again, going to try a gatorback belt this time.
While the belt was off, checked all my pulleys for movement or noise. ok
Cleaned out the grooves on the powersteering pulley with a metal pick to get out the
debris. then sprayed brake cleaner on all the pulleys. Then blew with shop air.
I found my alternator has been changed before and the pulley looks like it had been dropped before. Has a dent on the face of it causing the belt to ride in and out.
going to try and get a replacement. Need to drive it to work until i get one.
Installed the new belt and all noise gone for now. Hopefully it stays gone this time!
Note, I sprayed with water, noise went right away then came back even louder. So I knew i
had some miss alignment somewhere, but it never quit making noise to work and back.
It was very embarrasing :rant:

Buy a Gates brand belt... This took care of my squeak.

Re: Cold start belt squeak

Replace the alternator pulley. If you can noticeably observe the belt being affected, that's the source of the noise. The Gates site mentions a short span from a small pulley into a larger one is the most likely to become noisy. That's the alt into the PS pulley description for sure.

I replaced everything also...I still had the squeak....I spent alot of money because of cheap belts...

Very frustrating.

update 2, I got a new alternator pulley. got it changed out lastnight.
I had a new gates belt already, so i changed to a new gatorback goodyear belt for like $28
Napa said they would take back my gates belt! As of now i have no belt noise.
Hopefully it will stay quiet longer than 3 months. thanks for everyones advice and replys.
