Detailed Description

This A/C expansion valve is used in the refrigerant circuit to reduce pressure before the evaporator, allowing the refrigerant to absorb heat more effectively. For 2019-2020 INFINITI QX50 models, Global Parts 3412043 provides the correct service solution when replacing a worn or restricted expansion valve. This part cross-references Four Seasons 39644 for the same application.

What It Helps Address

• Weak or inconsistent cabin cooling
• Restricted refrigerant flow at the evaporator
• Improper A/C system pressure balance
• Cooling performance loss after A/C service
• Expansion valve wear during system repair

Installation Notes

Install Global Parts 3412043 during A/C service with the system properly evacuated and recharged. Inspect related components for contamination, leaks, or restriction before returning the vehicle to service. For 2019-2020 INFINITI QX50 repairs, verify the replacement matches the original valve style and refrigerant circuit layout.

Quality Assurance

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