In Reply to: Will Ester destroy my R-12 A/C system? posted by Michael on August 11, 2001 at 17:43:45:
Check the sticker at the hood hinge area and check your A/C fittings.
Have you owned the car since new? If not the previous owner may have convert it.!
I brought my 1988 735i in to what I believed was a reputable local A/C shop to have them replace the condenser which was leaking. They added about 1.5 or so ounces of ESTER to the new condenser to replace the oil in the condenser that was removed. I did not know enough about A/C at the time and only after the job was finished did I question what they did. Can anyone give me an opinion as to whether or not my R-12 system will be damaged/destroyed because of this action?
