Thanks amx, I was just affirming the post about possible mixing of refrigerant (George's post). The old refrigerant was R-12, I never heard of 112. Here is a pretty good history of R-12 and the newer R134a ( http://en.wikipedia.org/wiki/Dichlorodifluoromethane ). Whatever is being used, the post from bdh said something about industrial 12a. George's post related to that, and I commented on George's post about mixing refrigerants. I did not know the killer chiller was a second 'zone' on the car A/C system. Like George said, only R134a should be used. If something other than R134a was installed in the car A/C system, it'll be extremely expensive when it (the system) totally fails
