i cant figure it out. ive had it before and it was the tensioner.

A little water on the belt stops it for a couple seconds and so does some lube but im avoiding doing it as it really doesnt help. Idk i feel as though that stuff makes the belt slip and it needs to grip.

heres my checklist of things ive replaced.
new belt (gatorback)
new tensioner,
all idler pulleys replaced, which is 2 i believe
new alternator
new power steering pump and pulley
new ac compressor
still does it! i have a water pump ready to go in, although its not leaking that i can see or feel.

im stumped.

one thing that really pisses me off is raising the engine in order to release that tensioner. Before i had a good year tensioner and my ratchet fit perfect. This time i got the cheap duralast and my ratchet wont fit.

Its probally too big of a belt if a little water will stop it and it is tightened all the way. How far does the belt flex downward when you push on it? If it flexes more than a quarter of an inch the auto parts store probally gave you the wrong size belt.

I get the gatorback 4060868.
I managed to shut it up with another new belt. But the problem returned. Everything is new.
Yesterday i resorted to belt dressing. Shut it up for half the day and it started up again! Even louder and now it does it all
the time where before it was when i hit the gas.

This is frustrating me to the point that im thinking of just junking the car.

Damn i feel your pain.. i just started having this problem again recently too.

When i was back in the mid-west about 6 months ago it was chirping real loud, i figured it had something to do with the moisture/humidity in the air because when i got back to Denver it stopped.

But now its back again!

Is There a way to check the belt alignment?
How far in should the power steering pulley be on the shaft of the pump?

i had some belt squealing a while back so i replace my belt and then a couple months later i had a completely different squealing and it turned out to be the ac clutch after i replaced it everything was all good

Run it and let it squeal for a least 5 minnutes. Shut the car off and see if any of the accesory pullies are overly hot. If for exampe, the alternator is hot, it is not the belt, but instead the bearings in the alternator.

well everything has been replaced and its all under lifetime warranty. hopefully its not some factory failure. It might go to the mechanic again tomorrow.

on a belt. nothing without shortening the life of the belt.
on the pulleys use brake cleaner and a rag.
also same could be done to the belt but will end up making the belt worse.

Hmm i used brake cleaner but it striped some of the paint off the pulley's.
The belt is my 2nd new one. Im trying to find the reciept so i can return it

Clean all your pullies with something like electrical contact cleaner.
