Noisy drive belt pulley

[DonFrancis]

when I start my car ....until the engine heats up I get this high pitch noise from a drive belt pulley...what can I do to resolve this issue?

Is it like a squeak? I thought it was my supercharger pulley, so i wd40d it and some dropped onto the other drive belt and made it worse, but once it got over it it was all good and the squeak still remains. While the engine was running i then loosened the pulley adjuster with a spanner to check, turns out it's one of my belts (before it even looked like it was crap). My drive belt now is starting to fray, i just need to get around to ordering the racing belts!

Some of those pulleys when you take them off theres a small bearing pressed into them. Just press it out and go to CBC and take it as a sample. Press back in and your away. If its just the belt WD40 drys out, you need some drylube. Supercheap should stock it.
