How to Add Freon to a Car?

[DiDiana]

The steps for adding Freon to a car are: 1. Before adding refrigerant, prepare the necessary tools and materials, including a car refrigerant recovery and charging machine and refrigerant; 2. Connect the hoses of the car refrigerant recovery and charging machine to the high and low-pressure pipes of the car's air conditioning system—red for the high-pressure pipe and blue for the low-pressure pipe; 3. After ensuring the hoses are correctly connected and the refrigerant recovery and charging machine has completed its self-check upon startup, proceed to evacuate the car's air conditioning system; 4. Only after the evacuation process is complete can you begin adding refrigerant. Set the charging capacity, time, and type on the refrigerant recovery and charging machine according to the maximum refrigerant capacity specified for the vehicle's air conditioning system. Once confirmed, the machine will automatically start adding the refrigerant.
