:help07 gmc 3500, i have a squeel thats sounds like a belt but its not and it wont make a sound till the truck warms up in between the rpm of 1300 - 1600 under a load only. i cant make it make a sound when the truck is sitting steel. it is driving me nuts!!!
i have put 2 new belts on and it didnt make a diff.

Have you checked the ac compresser pulley yet? Could need and ac compresser pulley. my truck did this when the ac compresser was running and when i was bulding up rpm but sopped when the engine warmed up n i replaced the belt and it fixed it..

How's the steering/brakes?

Pry the P/S pump pulley toward the front of the truck and see if you've a broken pump shaft.

Just a thought...

 

[lukejr]

Did you ever locate what was causing the whine in your truck? I've been searching for a similar noise and I'm having a devil of a time trying to locate it.

I had squeeling only when cold since the truck was new, once it warmed up it was barely noticeable. Had it to the dealer 3 times over 3 months time. 1st time replaced belt 2nd time adjusted pulleys, 3rd time left truck with dealer overnite so they could get it cold, replaced idler pulley. Its been a week and all ok. Doesnt seem like the same truck.
