Squeaky belt

Ok guys there is my problem, I sold my caddy so I will be using the Ty for now until I find another daily not that I drive it everyday but the belt is squeaky. I put a new serpintine on it so I know it is not a worn belt but when I put it on it jumps and cuts one grove off the belt. I figured maybe I didnt get it on right so I bought another belt and made sure it was on in the right spot and it did it again. I was wondering if maybe I have a bar pulley somewhere or what would caust this? It is also squeaky at idle and get a little louder when I am driving. Not a squeal yet but I dont want it to get to that. Once it cuts that one grove off the belt it is fine and does not move after that. Any ideas of what it could be?
 
Re: Squeaky belt

Could be an alignment problem with a pulley or accessory. Are all bolts in place and tightened? Could be bad bearings on one of your accessories allowing wobble. Possible something (hose clamp, custom bracket, etc) is making contact with the edge of the belt. Suggest you eyeball all the accessories to make sure they're in the same plane. Also watch the pulleys while engine idling. If you're still having a problem, the next time the belt is removed grab each accessory's pulley and see if it has slop. Good luck

Re: Squeaky belt

I had a similar problem on my Typhoon. Turned out to be the bolt and bushing that holds the idler pulley. It was off just enough that caused the belt to travel to the edge. Know that the aftermarket setup was what went wrong. The aftermarket stuff wants you to reuse the bolt and it was the bolt that had the ware. I had to pay the big bucks to get the genuine GM part because it came with all new stuff.

On my 2 wheel drive S10, I didn’t have the pulley problem but the belt squealed at idle. It was embarrassing. I tried dressing and stuff. Worked for a short time. What really fixed it was a gator belt. It has extra ribs on both sides. Problem went away.

Hope this helps.

Re: Squeaky belt

Let me clearify a little guys I guess its more of a click than a squeak. Doesn't get louder when I'm on or off the gas really that does not matter. I am leaning more towards a bearing or something any ideas what one could be b ad?

Re: Squeaky belt

no experience with this but have you looked at the ribs on the pulleys for damage? or something stuck in between the ribs?

Re: Squeaky belt

I don't think that is it either because I just had the whole motor apart a few months back to rebuild it and I probably would hav e noticed that but I will definatly take another look at it later and see. Thabks!

Re: Squeaky belt

Problem solved it helps when you put the belt around the pulley for the AC pump! Damn it I can't believe I missed it but its all fixed now. Thanks for the help guys.
