I'm going to be doing a full A/C system replacement on the truck in my signature. Compressor, evaporator, condenser the whole thing. This will be the first major A/C work I've done and I've got all the tools lined up. The compressor I have is a NOS motorcraft and has mineral oil in it, so I'll have to pour out that and replace with PAG 46. I know the original specs were 52oz of R12 and 10 oz of mineral oil. Last time compressor/condenser was replaced they used 40oz of R-134 and 10oz of PAG 46. Does this sound right? Also do you just put all the oil in the compressor or should I put some in the condenser and evaporator when I install?
