Squeaking noise?

[cobra2798]

Last week I installed my underdrive pulley's and now im getting a loud squeaking noise coming from that area. Im not sure if its the pulley's themselves or if its the new serpintine belt I put on with the pulley's. Is this normal with new pulley's or a new belt? would some belt dressing fix this or can I do something else to quiet it down. the car runs great and the noise is not effecting performance. Can I get some help guys?

did you use the same belt? im thinking the belt is too long.

Its a new belt and a 1/2 inch shorter than stock.

hows the tensioner reading?.... between the lines?

maybe they have some coating from manufacturing that needs to dissipate

Ensure the pulleys are all in alignment (a machinist's straight edge can help). If one pulley is a little cockeyed, the belt will squeak.

Personally, I would not use any belt dressings.

Good luck.

I agree with Hissin 100%. I bet one of the pully's is out a little and needs to be aligned. I have a little tool for aligning pully's it's a plastic piece with groves like a belt that fits in the pully with a laser that points to the other pully's when you turn it. But a strait edge works good.

Just took a look at it and it looks like my water pump pulley has a little wobble to it, could this be the problem? I thought I got it seated on there right.

yea, are the bolts all the way tight?

As tight as I can get them, ill take the pulley off and reseat it and see what happens.

As I recall, the hub under the WP pulley can get kinda rusty. Might take a little quick sanding/scotchbriting to get clean surfaces again.

Good luck.
