So i replaced the a/c compressor tonight and recharged the air con system so i finally have cool air and the cracking creaking noise from the faulty clutch pulley is now gone...........but
The high pitched noise is still there, which i didn't think this wasn't related to the a/c but was worth a shot as it needed done anyway, so back to the drawing board, I'm still thinking turbo myself but its hard to pinpoint from the drivers seat where the noise is coming from considering i can only get the noise to happen whilst driving
next job is the radiator and headlight washer hoses from the bottle as they have broken up with age so its capped off at the pump just now to stop it leaking
