    Comments about Dorman - Help Air Conditioning Bypass Pulley:

    This is a nice product. Went out to start my truck and the AC compressor was locked up. Don't really drive the truck that often so no need for AC. This was a much cheaper alternative than buying a new compressor. Only con it would be alittle easier to install if it had a diagram for the spacer placement.

        You have to remove the A/C compressor for one. You need to completely take it off the engine.
