Not for a trac but I'm pretty sure it would apply to most autos. GF's focus needed a new compressor. A friends dad who is a Chevy mechanic did us the favor and swapped it out for free. Turns out the compressor fit but it was the wrong one and the pulley's didn't line up. Somehow he didn't notice (insert chevy jokes here).
Anyhow, had the system drained and did the swap with the correct compressor myself. Added some 4oz of oil to the compressor, this was what was suggested by a few phone calls though I'm not sure if it is the correct amount. That being said, the oil is supposed to be drained from the old compressor and the same amount added to the new. For whatever reason, when I tried to drain the old oil nothing came out, at least, not until I got it to the parts counter. By then it was too late. Hence adding 4oz.
So I charged the system and I seem to have compressor knock. I'm trying to figure out how to proceed. I'm thinking, remove the r134, remove the oil, replace with half as much and recharge and go from there. This is pure guessing as I don't know if there is a better way to measure the current oil in the system.
Anyone have any ideas or suggestions, aside from an a/c shop.
