    Default A/C amount Freon

    I have a 157 continental Markll with factory air. Can anyone tell me the number of ounces of R-12 it holds . Most cars today take 2 12 oz cans of r-134. I have installed 4 cans of R-12 and it gets cold .The gags show the low side pressure 30 the high side 200 in 95 degree heat here in Kansas. The problem it takes too long to get cold ,so I feel I do not have enough R-12 .and do not want to overcharge. can anybody give me that information and any other advice I should know.

    This is the first time I have sent in a thresd,i guess that is the right terminology.

    Thanks Donald F Lett

    Unless 57's are different than 56's there is a sight glass in the trunk that should be free of bubbles when the system is full and turned on.

    Yes you are right and I appreciate your response. the problem with the sight glass because of the age of the sight glass you cannot see Freon or bubbles because of the acclamation of residue over the glass making the Freon or bubbles not visable. so the reason I wanted the quantity was with the unit pumped down I put in 4 cans 48 ounces ,now I could put in the remaining amount that is specified. So I still need the total amount of FREON. If you know someone in the forum that knows I would appreciate there names and how to contact them.
    THANKS
