Should the car air conditioning pressure test be performed on the high or low pressure side?

[DiAdaline]

Car air conditioning pressure testing is performed on the high pressure pipe. Below are specific details about car air conditioning high and low pressure pipes: 1. Usage: Generally, car air conditioning pressure testing is performed on the high pressure pipe, while vacuuming is done through the low pressure pipe. 2. Pressure test explanation: Under normal circumstances, the car air conditioning pressure test typically reaches about 20-30 Bar. If the air conditioning pressure can stabilize at 20-30 Bar, it indicates that the air conditioning leakage issue has been resolved, and the car air conditioning system has good sealing performance. Only then can the vacuuming and refrigerant charging procedures be performed.
