isx cm871 coolant pressurized

Good on the cooler lines. Are you having to add coolant on a regular basis or is the coolant staying in the system and just fluctuates the level? If you are losing coolant, and cannot find the source, tighten all of your clamps. If the system is pressurizing, it is either your compressor or head... But you know that. If you are plated off, I am thinking it may be your head... How are your EGTs?
