oil charge would be the ammount of oil required in the system. compressor's usualy come prefilled yes. When charging the system you will need to have it atleast vacuumed, and I would recommend a pressure test to make sure it doesnt leak.Hmmm, I know of a coolant charge and the compressor oil, but what's an oil charge?
In that vein, I've been worried about the oil. Can you give me some details? Does the compressor come prefilled? In terms of charging the system with 134, do I need to have it flushed and/or vacuumed first? Thanks!
Just ask if theres anythin else you want to know its my job!
