Global Parts 3411934 A/C Expansion Valve - Front

A/C Expansion Valve for GM HVAC Service

Global Parts 3411934 is an A/C expansion valve/orifice tube that regulates refrigerant flow before it reaches the evaporator. By slowing refrigerant at this point, it helps the system use cooling capacity more effectively in GM truck and SUV applications.

Detailed Description

Global Parts 3411934 is used in the HVAC system to reduce refrigerant pressure before the evaporator, allowing the refrigerant to absorb heat more effectively. This makes it a practical replacement during A/C service on vehicles such as the Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade, as well as select Silverado and Sierra models. Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced to maintain proper refrigerant control.

Common Repair Uses

• Restores weak or inconsistent cabin cooling
• Addresses restricted refrigerant flow in the A/C circuit
• Helps correct evaporator feed issues after HVAC service
• Supports repair of temperature fluctuation in GM A/C systems
• Replaces a worn or contaminated expansion valve/orifice tube

Installation Notes

Verify the vehicle application and position before installation. This part is listed for front and N/A positions depending on the vehicle, so match the fitment exactly to the service location. Inspect the A/C system for contamination or restriction before installing the new valve, and follow standard refrigerant recovery and evacuation procedures.

Quality Assurance

Global Parts supplies this HVAC component as a service replacement for select GM applications. The manufacturer recommends renewing the expansion valve/orifice tube whenever the A/C system is serviced to help maintain proper refrigerant metering.
