So my belt was squeaking, naturally I changed the belt. It still squeaks, which must meanit'sone of the pulleys. But the squeak goes away after about 5 min. of the truck running from a cold start. So it has someting to do with the belt and/or pulleys heating up that makes the squeak subside.
I tried listening the best I could to find out what pulley may be squeaking but can't quite tell. I don't think its the idler or tensioner.

Any ideas about this or common fixes or pulleys that usually squeak?
Thanks

 

While the truck is running get a candle (not lit) and press the candle against the outside of the belt while running making sure you cover the entire belt and it will stop squeking.

 

The belt tensioner on mine was doing the same sorta thing, it squeaked when it was first started, pretty badly, but would go away after a few minuates. I changed the belt first too, thinking that was it, i shot some wd40 on the tensioner and the squeak went away right after that, so I had to change the to take care of the problem. Don't know if thats helpful, but that was my problem.

 

Yah my tensioner needs to be changed again this will be the third total,the first I will install.

 

OK so I changed the idle pulley and still squeaks. Of course the squeak goes away when the vehicle warms up. About 5 min. I can't figure it out. Any ideas? Tensioner?
