Solution

1. Preparation

Tools Required: Safety goggles, gloves, and a refrigerant recovery machine.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety goggles and gloves for protection.

2. Recover Refrigerant

Connect the refrigerant recovery machine to the AC service ports.
Turn on the machine to recover the remaining refrigerant in the system according to the manufacturer’s instructions.
Ensure proper disposal of recovered refrigerant in accordance with local regulations.

3. Repair the Leak

If the leak is from a hose:
- Remove the damaged hose by loosening the clamps with a socket set.
- Install a new hose, ensuring all connections are tight and secure.
If the leak is from the AC compressor:
- Disconnect electrical connectors and remove mounting bolts.
- Replace the compressor with a new unit, ensuring to properly torque bolts to manufacturer specifications.
If the leak is from the condenser or evaporator:
- Remove the front grille (if necessary) and detach the condenser.
- Replace the condenser or evaporator and ensure all seals and gaskets are new and properly installed.

4. Recharge the System

Use a vacuum pump to evacuate the system for at least 30 minutes to remove moisture.
Connect the refrigerant charging hose and refill the system with the appropriate type and amount of refrigerant as specified in the vehicle’s service manual.

5. Test the System

Start the engine and turn on the AC to check for proper operation.
Monitor for any signs of leaks and ensure the air conditioning is cooling effectively.
