• Cross-references Four Seasons 39480 for the same application

Detailed Description

This expansion valve is used in the HVAC refrigerant circuit to meter refrigerant before it reaches the evaporator core. That metering step is critical for stable cooling performance and consistent cabin air temperature. Global Parts 3411519 is listed for 2013-2022 Buick Encore, 2012-2020 Chevrolet Sonic, and 2013-2020 Chevrolet Trax, making it a focused replacement for common GM compact-platform A/C service needs. The part number 3411519 is also useful when searching for an OE-style replacement by number.

What It Helps Address

• Weak or uneven cabin cooling
• Incorrect refrigerant metering at the evaporator
• A/C performance loss after system service
• Restricted refrigerant flow in the HVAC circuit
• Service-related replacement needs on Buick Encore, Chevrolet Sonic, and Chevrolet Trax

Installation Notes and Tips

Replace the expansion valve/orifice tube during A/C service when the system is opened. Verify the vehicle application by year and model before installation, and inspect the surrounding HVAC components for contamination or wear. Proper evacuation, leak checking, and recharge procedures are required after service.

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.
