I have about a day or two of work left before I start up my car and I have
an A/C compressor question. The last time I drove this car was in 1990.
It's been parked since then. I assumed that all the freon (R12) had leaked
out but when I checked, it was still pressurized.
My question is, would it be safe to put a belt on the A/C compressor and see
if it works when I'm ready to start the car? The compressor and the pulley
turn freely and independently (by hand). The compressor "old style" GM,
about 1 foot long.
Since the car has been sitting for 14 years, is there any maintenance that
the A/C system requires before trying it out? I expect that I'll have to
add freon, I just don't want to damage the system if I can help it.
