How do you change expansion valve on 2001 Mitsubishi Montero sports?

To change the expansion valve on a 2001 Mitsubishi Montero Sport, first, ensure the A/C system is fully discharged to avoid refrigerant exposure. Remove the dashboard or components blocking access to the evaporator case, then locate and disconnect the old expansion valve's refrigerant lines and electrical connections. Replace it with the new valve, reconnect the lines securely, and reassemble any components removed. Finally, recharge the A/C system and check for leaks.
