Global Parts 3411320 A/C Expansion Valve - Rear

Global Parts A/C Expansion Valve 3411320

Global Parts 3411320 is an A/C expansion valve for rear HVAC applications. It meters refrigerant flow before the evaporator so the system can use cooling capacity efficiently in compatible Cadillac Escalade ESV, Chevrolet Suburban, and GMC Yukon XL rear air conditioning setups.

Key Features

• Expansion valve/orifice tube style A/C flow restrictor
• Controls refrigerant flow before the evaporator
• Supports rear HVAC service on listed GM applications
• Global Parts part number 3411320
• Cross-references DENSO Auto Parts 475-2056 for the same application

Product Details

This Global Parts 3411320 expansion valve is used in rear A/C systems where refrigerant must be reduced and regulated before entering the evaporator. That pressure drop helps the evaporator absorb heat more effectively, which is important for stable rear cabin cooling in vehicles such as the Cadillac Escalade ESV, Chevrolet Suburban, and GMC Yukon XL. Global Parts recommends replacing the expansion valve/orifice tube whenever the A/C system is serviced.

What It Helps Address

• Weak rear air conditioning output
• Irregular refrigerant metering at the evaporator
• Restricted cooling performance in the rear HVAC circuit
• Service-related contamination in the A/C flow path
• Restoration of proper refrigerant control during A/C repair

Installation Notes

Verify the rear HVAC configuration and match the vehicle application before installation. Inspect the A/C system for contamination, leaks, and related wear before replacing the valve. This part is listed for rear position use on the specified GM applications, including 1996-2006 Chevrolet Suburban variants and 2000-2006 GMC Yukon XL models.

Quality Assurance

Global Parts supplies this component as a service replacement for the listed applications. The manufacturer notes that the expansion valve/orifice tube should be replaced each time the A/C system is serviced.
