How to Release Freon in a Car?
1 Answers
To release Freon in a car, follow these steps: 1. Connect the manifold pressure gauge to the compressor and the refrigerant tank. 2. Open the refrigerant tank, loosen the nut on the middle injection hose, and tighten the nut after hearing the sound of refrigerant vapor flowing to expel air from the hose. 3. Open the low-pressure manual valve to allow refrigerant into the cooling system, and close the manual valve when the pressure reaches 0.4 MPa. 4. Start the engine and turn on the air conditioning, setting both the fan speed and temperature to the highest levels. Open the manual valve on the manifold pressure gauge to allow more refrigerant into the cooling system until it reaches the specified value of 1.37 to 1.67 MPa.
