Thread: Squeaky squeaky

Ok so, my supercharger tensioner has started to squeak real bad. Im not sure if Im supposed to replace the pulley or the tensioner. :/

^BUMP

Best I can tell you is..

We don't know either. From what you've posted, you have a squeaking issue. Could be belt, tensioner or pulley.

Did you look at the tensioner to see if it's in the normal range of operation? yes, there are marks on it.

Just had a giant cricket in the gtp. Took off the front smooth pulley, cleaned the carbon/filth off, and lubricated the bearing area. Squeak gone... for now.

I didn't mean to be so vaugue. I do know that the pulley was replaced within the last two years. So that rules out the pulley. I think the supercharger belt may be loose, its only been on the car nearly 4 years lol, or the tensioner is going bad it is an original tensioner as far as I know. No I haven't checked.the lines om the tensioner, not yet. I had planned on starting with a new belt.

Cheaper thing to do would be to untension the belts and spin all the pullies. 2 years means nothing to a manufacturing defect etc. Maybe the pulley's bearing wore quick. Maybe the belt isn't tracking straight.

Maybe another pulley is about to fly off the car.

I will check all ove the above. Thx.

Could be a bearing...and if your pulley is plastic, ditch it for a Gates replacement from O'Reillys that's metal. The only pulley you cant change thats plastic both stock and a replacement is the grooved one on the coil bracket. Your stuck with it being plastic. But you can replace the idler, and the tensioner with metal ones if yours are plastic.

Might also check and see what pulley you have on your serpentine belt tensioner (kinda under your alternator there) if its plastic, I would loose that one too for a metal one.

IMO.

~F~

I know my idler pulley is plastic, ive replaced it. The tensioner puller is metal. Thx for the help all.

I have a problem with the advice of swapping to metal. The plastic pullies do last a very long time, as do the metal ones. The problem area is the bearing. Both bearings from my research are made by the same place and pressed into both pullies. The bearing is the part that goes bad, does it really matter what is wrapped around the part that goes bad?

With metal the belt gets destroyed and fails, with plastic the belt burns through it, gets destroyed and fails. Either way..if a bearing fails.. your in the same place, beltless.

The only advantages I see would be running plastic. Because of the lighter rotating mass. Although I doubt the difference in weight is material to performance.

My advice is use whichever one you choose. And BTW if you look up the pulley thread I posted, there is a metal grooved pulley available.

When the bearing goes bad that means time for a new tendioner?
