R33 Belt Squeal

[SargeRX8]

Hey all,

Ive found it literally impossible to determine which belt is causing the squeal but its embarrassing. Everytime I stop at lights, it squeals. Slowly accelerating, it squeals. My only solution is spraying wd40 on the belts everytime I pull out of the drive way.

I was trying to narrow down which belt it was and by sound, I can't. Is there a technique? What I did notice though is the alternator belt is not spinning straight. When you watch the belt as it rotates it isn't like sitting in one part of the groove. Its hard to explain but its not like staying straight. From top view the belt looks like its not aligned. Its not loose though.

Any ideas? How much to change this? Could I do it my self?

i think there is a aerosol can out to stop belt squeak mayb at autobarn, only temporary but mayb could use it to find out what belt is squeaking if you do one belt at a time??

belts are one of the more simple things to work on in a car.

i would be concerned about that misalignment... the alternator belt also does your water pump, so it's kinda important. maybe check that it's the correct belt type? your alternator/ air-con belts should be 4-peak and the power steering should be 3-peak (the peaks are on the underside of the belt as they are ribbed belts).

if someone has put a 3-peak on the alternator, it might be sitting in the wrong grooves which is what makes it look funny as well as making it squeal as it is rubbing wrongly on the pulley.

you could always take off all the belts and have a good look at their condition (cracks, fraying or looking too shiny are bad) and make sure the correct ones are all there. i don't know all the belts off the top of my head, but the air-con is a 4pk910 and the alternator is a 4pk865 (or about that, the first number is number of peaks, the second number is the length of the belt). power steering is a 3pk###. this is all based off my R33, so it should be the same for yours.
