A/C Pressure Test/Diagnosing in cold ambient temps
Question is:
If the ambient temperature (car parked outside since I don't have a big enough garage to work in) is between 35-40 f (around 0-4c) what pressure should the car be having? Service Manual states: When the refrigerant volume is correct, the gauge reading indicates as follows: Low pressure side: 0.15 to 0.25 MPa (1.5 to 2.5 kgf/cm2) High pressure side: 1.37 to 1.57 MPa (14 to 16 kgf/cm2) HINT: Pressure varies in accordance with certain conditions (outside air temperature, sunlight and wind). |
