How It Works

The expansion valve reduces refrigerant pressure and regulates flow as it enters the evaporator. That pressure drop helps the refrigerant absorb heat more effectively, which is essential for stable cabin cooling performance. Global Parts 3411969 is built for front A/C service on vehicles including the Chevrolet Traverse, GMC Acadia, and Buick Enclave.

Common Problems It Can Address

• Weak or inconsistent front A/C cooling

Installation Notes

Verify the vehicle year, make, model, and front HVAC placement before installation. Replace the expansion valve during A/C service when the system has been opened, and follow proper evacuation, leak-check, and recharge procedures. Confirm the refrigerant circuit is clean before returning the vehicle to service.
