1998 Chevy truck pressures

scoob8000 on Mon September 01, 2014 9:50 AM User is offlineView users profile

Year: 1998
Make: Chevrolet
Model: C1500
Engine Size: 5.7
Refrigerant Type: 134a
Ambient Temp: 80
Pressure Low: 35
Pressure High: 220

Anyone happen to have the pressure/temperature chart for a 1998 Chevy pickup (c1500) that I can save for my archives?

I just got this truck not too long ago. Just checking things over. The compressor is a little noisy for my tastes (kind of very very faint, hollow clacking sound)

Outside: 72f 95% Humidity - Reading around 46f at the center vent, blower on max.

At 2000rpm: Low 35psi High 220psi

Pressure stay pretty steady, not fluctuating or fluttering.

[Edit]
Checked it a again since it wasn't really warm this morning

Now we're at 82f, 75% Humidity. Low is right at 40psi, and high side right around 270
