Thread: Differences in ac compressors

    Default Differences in ac compressors

    A post in another members thread got me thinking about ac compressors. I have a remanned unit that has yet to be used on my 87. Its the older style. I know Ford changed then in what 89, but why did they change it? And is one better than the other? My 87 had no ac equipment, except for an evaporator that was cut, so I built it from the ground up. I had to use fox mustang suction and discharge manifolds at the compressor since I couldnt find ones for a box and theyre essentially the same. However the fox manifold has a low pressure port on it that hits the coil bracket. Its no big deal but Id rather use the correct manifold if I can. Enough of that though, in addition to the above questions, is it worth it to swap to a newer style ac compressor?

    I cannot comment on the compressors but if you want the correct manifolds let me know. I pull three sets from a junkyard and just did the swap on my car.

    Different manufacturer for the compressor, but I don't know if there is any real advantage to one over the other. The hoses are different, and that might be an issue. I don't know exactly when the various components changed, but the connections at the condensor and the drier aren't identical across all years. Depending what parts you have in the car, that might force you into specific AC lines, and that will determine the compressor. The FS6 uses the manifold and the screw in connections, whatever the later one is uses a line with a quick connect at the compressor manifold. Both of mine are the old FS6 pump, and it works fine. Neither have the updated condensor or anything else, its just the stock stuff that came on the cars in the 80s with R134a retrofit connections on the charge ports.

    I already have all the components (FS6) so thats the way Im headed but it got me thinking. I havent had much time to tinker with it but the last time my buddy and I tried to pull a vacuum on it there was a leak. Im pretty sure I know where it is and will solve it asap then hopefully will have ac. For the time being its going to have to sit unfortuneately.
