You will see about 30 lbs. suction and maybe 150 to 175 lbs. head at 1000 rpm's

At 86 degrees F, coming from the center vent, and engine rpm of 1,500, intake pressure should be around 57 psi and delivery pressure should be around 213 psi.
At 77 degrees F, the numbers should be 43 psi and 142 psi.

I have a 1996 Dodge 1500 4x4 360. My air conditioner is blowing hot air. Freon is good. But I have notice that the compressor kicks in and out every 8 to 10 sec. .
thank you

gstanley, you may need to replace the Thermostatic Expansion Valve (TXV). If you do, you should also replace the Receiver/Dryer.
