Belt squealing

[Eric]

I just replaced my serpentine belt about 3 months ago. (Replaced it with an OEM belt) It started squealing the other day when it rained. Now, it squeals all the time. Not terribly loud but noticeable. It's worse when it's wet outside. I put some belt spray on it today and that only made it worse. The belt has no signs of wear. What could the problem be?

Check the tensioner, see if any wheels/pullys turn with resistance.

Try a dab of silicone grease on the Back of the belt, just a 1/2 pea size should distribute across everything as soon as it starts.

I figured that belt spray that I bought would've had some silicone in it. Then again, I didn't read the can

Sorry for the but this may be useful for you.

I have a worthless shop manual for my truck and was wondering what's involved in replacing the tensioner and idler, a few bolts?... what's the torque spec? Gutentight?

I have a chirp when cold and I am replacing everything as PM when I do my waterpump. Grease trick didn't help much.

Where is the tensioner on it? If I was having that problem, Id try tightening it up some. I never looked to hard for a tensioner on mine, the one time I had the belt off, I took the alternator off, tilted it down, and used 2 screwdrivers in the bolt holes to tilt it up into place, worked great for me.

get some super glue and put some on the belt while its running. works every time
