A/C Refrigerant - ZR-1 Net Registry Forums

bb62 · 07-04-2020

I am trying to add refrigerant to my ZR-1(1995). There was previously under 10 lbs of pressure in the system. On my first 12 oz. can (which is not finished), the gauge reads well into the yellow zone (over 50 lbs). Theoretically I am not supposed to add to a point where the gauge reads in the red zone.

The car itself was turned on with the A/C system on. The A/C system was not cycling at that point at all. With the partial can, I am getting a clicking every 5 seconds or so, but no cold air. Since the system requires 2 lbs (or more than 2 cans) there is no way that it is full so I can get cold air, but why is the gauge nearly in the red. It is 86 degrees here (Fahrenheit). Thoughts?
