Global Parts A/C Expansion Valve 3411810

Global Parts 3411810 is an A/C expansion valve for front HVAC systems on select Chevrolet, Pontiac, Buick, and Saturn vehicles. It meters refrigerant flow before the evaporator so the system can use refrigerant cooling capacity efficiently.

Key Features

• Expansion valve/orifice tube design for A/C refrigerant control
• Fits 2005-2009 Chevrolet Uplander, front
• Fits 2006-2009 Pontiac Montana, front
• Fits 2005-2007 Buick Terraza, front
• Fits 2005-2007 Saturn Relay, front
• Fits 2006 Pontiac Montana, N/A
• Global Parts part number 3411810

Detailed Description

This A/C expansion valve is used in the refrigerant circuit ahead of the evaporator to regulate flow and pressure drop for proper cooling performance. Global Parts 3411810 is a direct-fit service part for front HVAC applications on the Chevrolet Uplander, Pontiac Montana, Buick Terraza, and Saturn Relay. This part cross-references UAC (e.g., EX9720C, EX10208C) for the same application.

What It Helps Address

• Weak cabin cooling caused by restricted refrigerant metering
• Uneven evaporator performance in the front A/C circuit
• Service repairs where the expansion valve is replaced during A/C work
• Loss of cooling efficiency after contamination or wear in the refrigerant path

Installation Notes and Tips

Install during A/C system service after recovering refrigerant and opening the circuit. Replace the expansion valve when the system has been contaminated, repaired, or serviced at the evaporator side. Verify the vehicle application and front-position fitment before installation on 2005-2009 Chevrolet Uplander, 2006-2009 Pontiac Montana, 2005-2007 Buick Terraza, and 2005-2007 Saturn Relay models.

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 performance.
