recently i replaced valve covers, spark plugs, ignition coils, o2 sensors, timing belt and tensioners, new belts thanks to this site and all whom are willing to post!.... but once finished i think i might have overtightened the ac belt cuasing my ac to go out. now the ac clucth does not engage. i think all i damaged was the ac clutch coil does any one know if the whole compressor has to be replaced or just the coil? also does any have pic they may have done this before?
