Where do you add refrigerant to a 2002 Mitsubishi montero sport?

To add refrigerant to a 2002 Mitsubishi Montero Sport, locate the low-pressure service port, which is typically found on the larger of the two AC lines, usually near the firewall or the front of the engine bay. Remove the cap from the service port, attach the refrigerant can or charging hose, and follow the instructions on the refrigerant can for proper filling. Always ensure the AC system is running and monitor the pressure while adding refrigerant to avoid overcharging.
