All lines and condensor and evaporator have to be thoroughly flushed because R12 oil and R134 are not compatable.
Who do you trust to remove the plenum?

I spoke with Marc H. He tells me the compressor, accumulator/dryer, orifice tube and O-rings are compatible with R134A. He also said the lines did not need to be flushed. Just need to evacuate the system, the mineral oil remains in the bottom of the accumulator and doesn't mix with the R-134A. I have evacuated the system and it is holding vacuum. I need to change the high side (AC 15-30419) and low side (GM 15-30420) Schrader ports and add 8 oz. of GM 88901445 PAG oil and then charge with R132A.
I trust no one to remove the plenum, only me.
