i had a very annoying squeal!!! turned out to be the dang water pump...

 

Check pulley alignment. CHeck to make sure the crank pulley isn't backing off any.

Do NOT use spray or soap. They work by breaking down a layer of the belt, making it tackey. Once the tackey wears off the belt, it begins to squell again. Repeating the process will ruin a good belt.

Look for wear on the belt. Inside and out. You may see frayed edges or something. That will be your clues. My bet is it's pulley alignment.

 

Also .. check the p/s pulley. I've heard of them breaking.

 

Thanks,
It looks like the idler pulley may stick out a bit to far..about an 1/8th of an inch.
would that cause the problem?


as far as the belt goes, this one is brand new.
it lets the tensioner sit on the middle line of the bracket.
the ones before this where to small, and caused the tensioner to sit on the mark on the right.

 

I had the same problem after the 6.0L swap. It ended up being my power steering pulley not being seated all the way. It only went an additional 1/16"-1/8" further on when I started re-pressing it...but that was enough to make a brand new belt squeal like a pig after about 30 miles.

It could also be your water pump. I would start by making sure all your pullies are fully seated then throw some parts at it. I doubt the idler pulley is the problem, usually a squeal is going to come from the grooved side of the belt.

 

well,
after a long hard day at work of looking at the truck, I took the Alternator pulley off, and noticed that the grooves of the pulley where to high.. they where riding in the bottom of the belt..
(if that makes since to any of you..)
basically the belt is suppose to ride on the top of the pulley, and not touch the top ribs of the pulley..( you can see where this is happening as the pulley will be very shiney where it makes contact with the belt)..
also the inner groves of the belt where glazed over..

I took the alt, pulley and ground it down, and then buffed it out..
now the belt rides where it should...
also bought a new power steering pulley as it was showing signs of wear..
you could see the

so far no squeelling from the belt..

it might have been the power steering pulley being out of alignment as well Colby..
but all is well now..
thanks for the help.

I'm betting on the p/s pulley. Glad to hear you got it fixed regardless.
