Re: Restoring and swapping a factory Air Conditioning system
R134 low pressures are lower than R12 and the high side is higher when under pressure (running) r134 is prone to leak when used in a r12 system. R134 systems have better seals and the lines are crimped different. I recommend that you do not use any refrigerant with stop leak or that has oil in it, add the oil seperate from the refrigerant. Just my opinion.
