Hi all,
I just started rebuilding the dash air of our 76 PB. I will be replacing the expansion valve, press switch, receiver-dryer, AC lines and compressor. It will all be converted to Duracool but first I will have it serviced with R134 basically because I want my AC guy to do the leak checks and service it with the correct amount of oil.
Anyway, my question is about the R12 oil that might still be in the evaporator and condenser. I understand the oil for R12 is mineral based and R134 is synthetic and the two are not compatible. This being the case is it necessary to flush the evaporator and condenser in order to clean out the R12 oil? If yes what procedure and solvent should be used?
Any suggestions would be most welcome!
Thanks,
Jon
