I have a 2006 Mazda 3 2.3L, with an ac compressor clutch that's basically falling off the compressor. They system actually still works (though it's not as cool as it should be). The compressor did not seize. But obviously I can't have a clutch that's rattling around. I tried to replace the clutch, but just couldn't ge the right part (it's not the original compressor). So I'm going to replace the whole compressor and the drier while I'm at it. I also have a small leak in the high pressure hose, so I'm going to replace that.
My question is. How do I make sure I end up with the right amount of oil in the AC system? I know I'm supposed to drain the oil out of the old compressor and make sure the same amount is in the new compressor. But I don't know how much oil leaked from the high pressure hose or how much might be in the drier. So how can I be sure I have the right amount in the system when I'm done replacing parts?
