The compressor is designed to handle refrigerant vapor at a specific density. Normal condensing temperature for most refrigerants is 110*F. R12 @ 110*=135 psig, R134a@110*F=145psig. Just change your oil to the new POE oil change the receiver/drier pull a good vacuum using a micron gauge if you know someone who has one. Charge it up with 134a and enjoy your cool air. I don't even know if my A/C works in my car, I have never tried it. It is like my radio. USELESS! I am an Industrial refrigeration mechanic.

Kuehl, stand up for me on this one..?
