Remove belt, clean all pulley surfaces, replace with new belt

the belt has no more than 2k miles on it....i felt it this morning and it does feel sticky due to the dressing...the belt stops squeaking a couple minutes into my drive but man its pretty annoying

Ok then how about remove belt, clean all pulley surfaces, replace with same belt

what should i clean the pulley surfaces with?

could be a bearing as well.

Could also b e your tensioner going out. How much play do you have in the belt?

the idler pully did have a slight squeal which cause my intial squeal when starting it up but it goes away within 45 seconds if that...there isnt much play with the belt... damn belt dressing should have never put that crap on!!!

Mine squeaks as well. I replaced the belt, Tensioner pulley, Idler Pulley and I dont have slack in my belt. Only makes a sound for a bout 10 seconds when she cold starts...

what could i use to clean that crud off my pulley surfaces

CanaryGT · May 25, 2011

I dont see why you couldnt just use an All Purpose cleaner. Like Simple Green.

O man, I did this to my car one time. After giving it the belt dressing treatment to fix a minor sound, the car squealed like crazy! I changed out the idler pulley, the belt, and scrubed every ribbed pulley with a toothbrush to get all that junk off & that took care of it. Belt dressing may work great for some, but i'm staying away from it from now on. Hope you get it figured out!

Squealing is usually caused by resistance to the crank pulley trying to move the entire system. I would bet its a bearing that's failed. They seize up and if you force it a bit, they warm up and start to rotate easier. I would check idle pulley or tensioner pulley for play, or wobble, or difficulty rotating. Sometimes people will bypass a pulley for a brief moment to eliminate possibilities.
