Bleed the air to zero by opening the tanks for the truck, then place a blocking plate (a silver dollar works) over the intake pipe to the compressor and putting the joint back together.

Then check for pressure buildup in the coolant system.

So the pipe that comes down from the intake correct? How long can I run the truck like that to determine if there's any pressure build up?
