G'day, I've got a high pitched squeal coming from one of my belts in my diesel gq, only on shut down. I only noticed it when i was waiting for my turbo timer to time out whilst standing beside the engine. Once the engine restarts its gone. The belts are all tight and look in good condition, and its only really started since i got back from fraser island. Any suggestions? Andrew

Try a little WD 40, maybe you have washed your vehicle due to the salt?
That way your belts were probably really wet. If not your belts may be ready to replace.
Cheers.

Is it an auto ?

Apparently if you rub soap on the belt it can reduce the squeel.

Cheers guys, I had been told that before to use wd40, but was sceptical about lubing the belts. I'll give the wd40 a go then possibly soap if it doesnt go away. And no it isnt an auto. Andrew

Andrew,

CRC "Belt Grip" in aerosol is good gear. With bit of care, you can spray on while engine is ticking over. Not OHS approved of course! Hooroo...

Andrew,

The CRC product becomes "dry" once it's sprayed on. Is especially good for belts that are too loose, or in emergency when it would not be wise to fully tighten the belt, because it may break. I reckon its good gear, and no, I don't work for them. Hooroo...

You could also try some chalk, dont use the WD because as others have said the belts are supposed to run dry and this will induce slippage.

Probably a sign to change the belt if you have tensioned it correctly. Keep the old for emergencies. Royce www.funshow.com.au

Andrew.
Squealing belts are caused by grit particles getting embeded in the rubber on the sides of the belt, the grit is machining metal of the pulleys, the best way to fix it is to hold a wire brush agianst the side of the belt while it is running, being very carefull to hold the brush furmly. Do not spray the belts with anything as the rubber compound is designed to work dry,

Andrew, whatever you do don't try using the wire brush on moving belts.... you may never see to drive again!
Take them right off and scrub them with the brush, it's slower but a darn sight safer.
I do this with my Discovery and it cleans the belt for a couple of months so it can be done a few times before replacement is necessary.
