1993 Ford Ranger A/C?

[Tony C]

I just installed a whole new A/C system on my 93 ranger. When I started the engine to fill the system with freon (134A), my head presure is so high, that my truck is trying to run hot when idling. How can I relieve that pressure, or what did I do wrong?

you could have installed the wrong size orifice tube, a line could have beed kinked or restricted, or it was overcharged.

either overcharged the system, or their is a blockage in the line, or the cooling fans are not on. any time the a/c is turned on the cooling fans must start right away.
