aux belt squeek or pulley?


Lude

Recommended Posts

car has started making the squeeling noise, not loud, but its there,

 

ive been under the car, and it seems to be coming fromt the power steering pump.

 

(its not a pump whine noise) its the aux belt sound, when you rev higher, the squeel noise becomes more freequent. sounds like a mouse squeek rather than a costant sqeel.

 

 

can i just put WD40 on the belt & the PAS pulley?

 

or will something need replacing.

 

 

PS the aux belt is only a few months old, and car doesnt run the tensioner arm (shorter belt as removed the air con)

 

any advice?

My car does this a bit. I reckon the cause of mine is the bearings in the power steering pulley wheel, but haven't been able to diagnose it properly yet.

 

Either one of the bearings or the aux belt would cause the squeak to get faster as the engine revs faster, so I don't think that eliminates anything.

 

I wouldn't put WD40 on the pulley: I've heard it's not good for moving parts. It's a water-dispersant rather than a lubricating oil IIRC. Try a light lube perhaps.

well if it does its probley not the aux belt, somebody tell me if im wrong but if its the aux belt then usauly when the engine get warms it stops sqeeling? i had the same problem with a sqeeling aux belt but the noise went once the enigine got warm! new belt and job was a good'un you could try taking the belt off and mnoving the pullys to see if the have any play or if they are making a noise?

I had this same problem half a year ago. I just took the aux belt of and put it back on and the noise was gone. Many people said that's not solving the problem but we are a half year later and the noise is still gone. Worth a try ;)

I haven't used mine for about 11 years, extremely hard use and never had a problem. Sounds like it could be the fanbelt tensioner pulley, try disconnecting the fanbelt and spin the pulley to see if the bearing sounds noisy.

 

How could it possibly be the fan belt tensioner pulley if he is not using one? :looney:

there are others running with no tensioner tho?

Or this. If Lude runs his car with no tensioner, he can't spin the tensioner pulley to see if it squeaks. ;)

 

I think someone's talking at cross-purposes here, could even be me.

No, I am pretty sure he's removed his air con pump, fitted a shorter belt, found the new belt run fouls the tensioner assemblie's damper bracket and damper that only manuals have, and he has removed the damper and the bracket(s) that it bolts to.? The tensioner arm itself, and the tensioner pulley remain?
