    Fox A/C compressor bench test?

    My 91 build will be getting A/C. I have all the pieces. Is there a way to bench test the compressor?

    Nothing specific that’s I’ve heard of, but if you know how the system works you could get a good idea by hand. First give the crank a spin by hand, then plug the holes and feel for a change, one side will be suction, the other discharge.
    Give the pulley a good spin too and check for any grittiness or noise, it should be smooth.
    Lastly you can energize the coil and check if it pulls in, usually a 9v battery will be enough, or you can use a 12v if you’re brave : )

    Even if it passes the above - it could still have a leaking seal(s).
    For the cost of it, i'd start with a new compressor if you can swing it.....in around $300 on RockAuto

    I may look into rebuilding it. Not a pressing issue since winter is coming and I move slowly, but kinda the way I roll.

    my build speed could be classified as a "generational project", sort of like a generational space mission where the launch crew's great grand children are the ones that arrive at the destination.
