Hi all,

A number of our families vehicles have noisy fanbelts - not the kind of noise that is made when they are loose (ie: a squeal), but more of a squeek.

Can anyone enlighten me as to what causes the belts to squeek and/or the best way to stop them from squeeking? My wifes car (a '93 Pulsar) is quite annoying and the noise is getting so loud that people turn and look at you when you drive past! :duh All the parts (belts/pulleys) appear to be in good condition and are correctly adjusted.

...and just so you know that this question is VW related, my brothers Type IV EFI Baja also suffers from the same problem... my brother blames the alloy pulley that he has fitted... but surely there must be a way to quieten it down?

Any suggestions?

The belt may have small cracks in the faces or
it may be out of alignment slightly or
the pullys may not be tight or
the belts may be too tight

I see you have checked all of the above

you can purchase a belt lubrication stick at most auto shops this is applied to the belt while its running WATCH YOUR FINGERS

you can also get away with some WD spray or even a cake of soap will do a similar job

I read it on FACEBOOK so it must be true

'dribble a wee bit of johnsons baby oil on the belt/pulley as the mtr is goin and the squeek magically dissappear for a few days.. '

Rub on some "Sunlight Soap"

(if your careful, you can do this while the engine is running.....with the usual disclaimers!!!!)
