    Depends on outside temperature. . What year car do you have, and what refrigerant are you using? The factory service manuals have pressure to temperature charts, but its different depending what AC system you have and what refrigerant you're using. I can give you R12 pressure charts but that may not help you.

        You're refilling with R12 then?



        Scan from the 86 manual, but it should be the same for 89 as long as its R12 yet.
