We had the system on a gauge and it was fine...I do not have the numbers but my friend who is a great mechanic said it was perfect. He also added a BG additive/lubricant to the A/C system and it helped a TON. A/C is blowing ice cold here mid summer in Central Florida. Only when I am in stop and go or idleing with A/C on does the engine get too hot. Fan clutch passes the friction test when at operating temperature.
