Global Parts 3411581 A/C Expansion Valve - Front or Rear

A/C Expansion Valve for GM Rear HVAC Systems

Global Parts 3411581 is an A/C expansion valve designed to regulate refrigerant flow before it enters the evaporator. By slowing refrigerant at the proper point in the system, it helps the evaporator use cooling capacity more effectively in GM rear HVAC applications.

This part is a direct-fit style replacement for select Chevrolet Traverse, Buick Enclave, Cadillac XT6, GMC Acadia, Cadillac Escalade, and GMC Yukon applications. Global Parts 3411581 is also referenced by UAC EX10407C and Four Seasons 39512 for the same application.

Key Features

• Expansion valve for automotive air conditioning systems
• Controls refrigerant flow before the evaporator
• Supports proper refrigerant metering in rear HVAC setups
• Fits select front and rear applications depending on vehicle
• Cross-references common aftermarket part numbers for the same application

Detailed Description

Global Parts 3411581 is used in HVAC systems where refrigerant must be metered precisely before it reaches the evaporator. This function is important for maintaining stable A/C performance in vehicles such as the 2020-2023 Chevrolet Traverse, rear; 2020-2023 Buick Enclave, rear; and 2021-2023 GMC Acadia, rear. It also applies to select Cadillac Escalade and Escalade ESV front or rear configurations, depending on model year.

For fitment-specific searches, this part number is commonly used when replacing a rear A/C expansion valve on a Chevrolet Traverse or Buick Enclave, or when servicing rear HVAC on a GMC Acadia. Global Parts 3411581 should be matched to the vehicle’s exact position and service configuration before installation.

What It Helps Address

• Weak or inconsistent rear cabin cooling
• Improper refrigerant metering at the evaporator
• A/C performance issues after HVAC service
• Expansion valve replacement during system repair
• Fitment needs for GM rear air conditioning service

Installation Notes and Tips

• Confirm the vehicle position before ordering; this part is used in rear and, on some applications, front HVAC locations.
• Several listed applications require hardware kit 1028308 for installation.
• Replace the expansion valve when servicing the A/C system to help maintain proper refrigerant control.
• Verify the exact model year and HVAC configuration for Chevrolet Traverse, Buick Enclave, Cadillac XT6, GMC Acadia, Cadillac Escalade, and GMC Yukon applications.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced. That service practice helps maintain consistent refrigerant control and supports reliable HVAC operation in the listed GM applications.
