Thanks very much for the help!
Of course, I have more problems now...
Before I started adding, there was no pressure (totally empty). Just
now jumped the compressor and now got 2 12oz cans of freeze-12 in there,
along with one of the cans of oil. My new question: although it doesn't
sound to bad at idle speed, as I increase the engine speed, at some
point (maybe 1500 rpms or so?) the compressor becomes really loud...
like something is knocking around in there in a way that it shouldn't
be. So, I guess my compressor is broke?
Next question:
I DO actually have another compressor. The '84 passenger van we haven't
sold yet has a compressor in it. It's A/C doesn't work because of
electrical issues that I didn't want to bother to fix. That system held
it's refrigerant. A year or so ago, I had someone evacuate the r-12 so
that I'd be able to remove the compressor. So it should be easy to do a
swap now, I guess.
So, is there anything should know about swapping compressors? Should I
be changing any seals, lubricating, etc., the old compressor I'm going
to put in there?
Thanks very much for any help, guys.
