Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Recover and Recharge Refrigerant

Tools Required: Refrigerant recovery machine, manifold gauge set, refrigerant.
Recover any remaining refrigerant from the AC system using the recovery machine.
Check the specifications for the correct type and amount of refrigerant for the XC60.
Recharge the system with the appropriate amount of refrigerant.

3. Inspect and Replace Components

Tools Required: Socket set, screwdrivers, AC manifold gauge set.
If leaks are detected, identify and replace the faulty components (e.g., O-rings, hoses, AC compressor).
Replace the cabin air filter if it is dirty or clogged.

4. Test AC System

Tools Required: Multimeter, thermometer.
Start the engine and turn on the AC to the maximum setting.
Use the thermometer to monitor the temperature at the AC vents; it should be significantly lower than the ambient temperature.
Check the AC compressor operation to ensure it's engaging properly.

5. Reassemble and Final Checks

Reinstall any components removed during the repair.
Ensure all fittings and connections are secure.
Perform a final check for refrigerant leaks and ensure system pressure is within specifications.
