Re: Converting factory AC to use R134a
I replaced my POA valve with the hi/lo pressure switch, flushed the system, and added the different oil required by 134a. I should have changed my condenser to a high flow as it doesn't cool as good as it should. In hind site I wished I had just had my POA re-calibrated and not gone with the switch. If you call vintage air I'm sure they could give some good advice on the necessary steps.
