Key Features

• Expansion valve/orifice tube design for A/C refrigerant control
• Fits 2007-2008 Mazda CX-9, front
• Supports proper refrigerant pressure drop before the evaporator
• Recommended for service replacement during A/C system maintenance
• Global Parts Part Number 3411838

Product Details

This A/C expansion valve is used in front HVAC systems on the Mazda CX-9 to regulate refrigerant entering the evaporator. By slowing refrigerant flow at the correct point in the system, it helps the evaporator absorb heat more effectively and maintain stable cooling performance. This part cross-references Four Seasons 39302 for the same application.

Common A/C Issues It May Address

• Weak cabin cooling on a 2007-2008 Mazda CX-9
• Irregular evaporator refrigerant feed
• Reduced A/C efficiency after system service
• Front HVAC cooling performance concerns
• Restriction-related refrigerant flow problems

Installation Notes

Verify the vehicle is a 2007-2008 Mazda CX-9 with front A/C application before ordering. Replace the expansion valve during A/C service when the system has been opened, and inspect related components for contamination or wear before reassembly. Global Parts Part Number 3411838 should be matched to the original application and refrigerant system configuration.

Quality Assurance

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