I am finally ready to install a rebuilt AC compressor along with a new expansion
tube and Accumulator in my 93 Lumina APV mini van. The factory manual has lots
of confusing info about adding oil as does the instruction that came with the
rebuild. They both say to drain and measure the oil in the old compressor and
use this amount to calculate the amount to add to the replacement.
Problem is, to get the old comp out I had to turn it every which way and all of
the oil just spilled out on my driveway so I did not get a chance to measure it.
So my question #1 is: Is it better to err on the side of too much or too little?
#2: The factory manual shows two compressor models, one has an oil drain bolt.
My model does not so I can only assume the oil goes in and drains out the Inlet
and/or Outlet ports, right? Does it matter whether inlet or outlet?
Thanks in advance for any answers advice or suggestions.
