ok i have a squeaky sound coming from my ac pully, when i turn on the car (97 camaro lt1) the squeaky sound is loud, if i spray some wd40 it will go away for a bit and then come back. so my questions is if the tension pully can be the prob or its the ac pully? and if its the ac pully how the hell do i take it off??? any tips would be appreciated, the noise is really annoying!
