What's the right way to remove the a/c compressor? Through the bottom or through the top (which seems to necessitate removal of the alternator). I need to change the oil in it for a R134a conversion. Also, how much ester oil should I pour in, and if it dosent all fit in the compressor for some reason (a problem I had in my peugeot, which probably wont happen here but I figured I'd as), is it ok to pour the remainder into the reciever dryer? Thanks!

Oh yeah, where's the high side port?

    With respect to Chris Herbst, who has done more of these than I have, I like to pull the alternator and remove it from above. It is much easier (for me) to loosen the tube fittings on the pump with the alternator removed.

    You can pretty much get it out the bottom easier than the top. It takes a little work but not too bad.

    The high side port should ("should") be at the back of the compressor. However, there is no guarantee that the compressor will have a high side port on it if it has been replaced (ever).

    About half the oil goes in the compressor, the rest in the accumulator.
