Hey all.

I need a little bit of education. AC compressor need to be replaced in C5 Corvette. Other than having to remove bunch of stuff like water pump, getting the compressor out is not an issue.

I have a neighbor with an AC machine that can evacuate the system. He can also re-charge it.

The question is with oil. What does it all mean? Repair manual says I need to measure how much oil I drain out of the old compressor etc.

Besides the compressor, is oil someplace else in the system? If I got a compressor that is pre-oiled, do I need to add more oil?
