Remove the cap from the service port, attach the refrigerant gauge and hose, and then add the appropriate type of refrigerant. Be sure to check the system pressure with the gauge to avoid overcharging. Always follow safety precautions and consult the vehicle's manual for specific instructions.

To install refrigerant on a 2000 Grand Vitara, first locate the low-pressure service port, which is typically found on the larger diameter line near the compressor. Ensure the vehicle is off, then connect the refrigerant canister's hose to the low-pressure port. Start the engine and turn the AC to the maximum setting; then, open the canister valve slowly to add refrigerant while monitoring the system pressure. Once the desired pressure is reached, disconnect the hose and check for leaks.
