How to Detect Where the Car Air Conditioning is Leaking Refrigerant?

[DiKing]

When a car's air conditioning system is leaking refrigerant, it is necessary to locate the leak for repair or replacement. Here are methods to detect refrigerant leaks in the air conditioning system: 1. Visual Inspection and Touch Method. Touch the aluminum pipes of the air conditioning system with your hands and observe if there are obvious oil stains on the surface. If oil stains are present, it indicates a possible refrigerant leak at that location. 2. Soap Bubble Test. Generate a large amount of soapy water foam and apply it to the air conditioning pipes. Check if gas bubbles emerge from the pipes. If the air conditioning system has a refrigerant leak, a large number of bubbles will form, identifying the leak location. 3. Use Specialized Tools, an Air Conditioning Leak Detector, for Measurement. If the leak detector emits a beeping sound at a certain location, that is where the refrigerant is leaking.
