Today I vac. the system down and added 2 cans of Duracool static. Then cranked the engine. The low gauge read 8# with the compressor running. When it clicks off the pressure goes up to 70#. Clutch pulls in again and the press. drops to 8#. I add another can of Duracool and get the exact same gauge readings. The dash air is about 60 deg. (90 deg outside) through this whole process.
You guys always talk about getting 20# on the gauge. Does that mean 20# all the time, compressor on and off? Should the pressure go up with the clutch disengaged?
Thanks,
