Seems that my 300D has a R12 leak. Unfortunately, R12 is expensive and hard to come by. I'd like to replace my valve cores without venting the system or hiring someone to evac it for me.

Anybody know if a ball valved R12 valve core removal tool exists??? These tools are readily available for r134a, but i can't find much for R12. Do our cars have anything unique/special about their H or L charging ports?




I think i still have some R12 in my system and i don't want to lose it. I'd wager that i have a leaking Schrader valve. My AC has been getting less effective for the past couple yrs and finally dipped to the point where it will no longer turn the comp on.

Thanks!
