If you are qualified to handle refrigerant, here are the steps on how to add Freon to a Range Rover:
1. Park your Range Rover in a well-ventilated area.
2. Turn off the engine and allow it to cool down.
3. Locate the low-pressure service port on the air conditioning system. It is usually located on the front of the engine, near the compressor.
4. Attach the refrigerant can to the low-pressure service port.
5. Open the refrigerant can slowly and carefully.
6. Allow the refrigerant to flow into the air conditioning system until the pressure reaches the desired level.
7. Close the refrigerant can and remove it from the low-pressure service port.
8. Start the engine and allow the air conditioning system to run for a few minutes.
9. Check the air conditioning system to make sure it is working properly.
Note: If you are adding Freon to your Range Rover, it is important to use the correct type of refrigerant. The type of refrigerant used in your Range Rover will be specified in the owner's manual.
