squealing belt/pulley
#1
#2
I have the same truck and mine will do the same, my 99 f250 will do the same after it rains. They also do it if snow gets in when its snowing hard. I've found that moisture sometimes gets held up under the belt on the pulleys. It has always stopped after a short amount of time though. Maybe try blowing it out with air and see if that gets the moisture out.

First, the belt will need to be replaced because the squealing has ruined it.
The long term fix with new belt in hand is to remove the Glazing on all the pulleys before putting on the new belt.
The original squealing caused this glazing and it will just continue squealing even with a new belt, and ruin that belt.
To remove the glazing use scotchbrite pad or wire brush on all the pulleys, idler and tensioner as well.
You want a rough surface for the belt to ride on, this is a friction driven system.
squealing = lack of friction

do you pull your pants up before wiping? lol clean the pullies first and then put the gatorback belt on or your problem may come back much quicker than you'd think.
I need to do this to mine. i occasionally get a squeal when it shifts into a new gear if im heavy on the throttle and in the rain, its really squeaky.

if after you clean your pulleys and it keeps squealing, then do what im about to recommend. I had 3 pulleys with oily residue on them after i replaced my intake manifold gasket.
take one of those hand held propane torches and burn the residue off. this will be your only viable option other than replacing the pulleys

Pull the belts
Clean the pullies with a cleaner and a small wire brush, more cleaner
Dry well
Get new belts, preferably Gatorback Belts.
That easy, don't try fixes, they will only add to the problem.
Belt dressing adds more $hit to the pullies adding build up and harder to clean later on, which will you will end up doing at sometime in the future.
