Global Parts 3411371 A/C Expansion Valve

Global Parts A/C Expansion Valve for Mitsubishi Diamante

Global Parts part number 3411371 is an A/C expansion valve for Mitsubishi Diamante applications. It regulates refrigerant flow before the evaporator so the system can use cooling capacity efficiently.

• Fits 1997-1998 Mitsubishi Diamante, N/A
• Fits 2000-2004 Mitsubishi Diamante, N/A
• OE-style A/C flow restrictor for refrigerant metering at the evaporator inlet
• Direct replacement for service work on the Mitsubishi Diamante A/C system
• Part number 3411371 for catalog lookup and ordering

How It Works

The expansion valve reduces refrigerant pressure before it enters the evaporator, allowing the refrigerant to absorb heat more effectively. This helps restore proper A/C system operation when the original valve is restricted, worn, or no longer meters refrigerant correctly. This part cross-references Four Seasons 39060 for the same application.

Common A/C Problems It Can Address

• Weak cabin cooling on Mitsubishi Diamante models
• Incorrect refrigerant metering at the evaporator
• Uneven A/C performance after system service
• Restricted refrigerant flow in the HVAC circuit
• Compressor cycling caused by flow control issues

Installation Notes

Replace the expansion valve/orifice tube during A/C service, as recommended by the manufacturer. Verify the vehicle year and Mitsubishi Diamante application before installation, and follow proper evacuation, leak-check, and recharge procedures after service. Part number 3411371 should be matched to the vehicle’s HVAC configuration before ordering.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced to help maintain correct refrigerant control and cooling performance.
