sqweeky belt on 2000 S-10

I noticed a sqweek of the belt on my truck that went away when I accelerated. I applied some belt dressing to the belt and the sqweek stopped when idling, but now it sqweeks twice as loud when I accelerate???? Was belt dressing a mistake? I have only put a few hundred miles on the truck since I bought it and it has about 39000 miles on it. I assume the belt is the original but I have seen worse that didn't make noise.

-common for the serpentine belt to start making noise at your mileage. Easy fix - replace it.

Agree. Belt dressing is a waste of time and will not fix the problem. Belt replacement will.

if your (unknown)style engine has an automatic tensioner, it's very possible the tensioner spring has either lost it's strength or is seized and not able to automatically tension the belt. look for a tensioner and put a wrench on it, it should move freely and be somewhat resistant(tight) to hold the belt on tight. it should also not be worn out to where it's out of alignment with all the other pulleys. this will quickly eat a new belt if not fixed(replaced)

i've seen this on a 4.3L once

let us know what you find

The tentioner was fine. The new belt did the trick.

Not sure if it is relevant, but make sure that you do not have oil or antifreeze getting on the belt. If there is any, that could cause the belt to squeak.
