How do you install refrigerant on 2000 Grand Vitara?

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.
