A/C is cool at idle and warm at 1000 rpm
My ac blows somewhat cold air at an idle, 60 deg F. When the engine is accelerated to 1000 rpm the temp raises to 70 and drops back to 60 when the engine is idled. The coolant pressures seem high and they fluctuate from 35 to 45 psi on the low side and 250 to 300 psi on the high side of the system. The compressor runs constantly.
Should I be getting pressures this high?
Does anybody have an explanation for the fluctuating pressures?
