I think Harold posted the pressure. I'm sure they are correct knowing him. But I have still found in my experience that let the gauges tell you what's going on. Be sure you turn the air on max, ac blower motor on max and the radiator fans on also. Then raise the idle and trust the gauges.

John, I live in Fargo, ND. The elevation is 900 feet. Do you have any tips on what pressures are appropriate at a given ambient temperature? I was going to buy a set of gauges since my Lexus has given me A/C problems in the past, too. Andy In a message dated 3/17/2007 10:55:42 A.M.

I would leave it to the gauges which will tell the real story as to what is going on in your system.
