Denso 475-2084 A/C Expansion Valve - Front

Denso New Expansion Valve 475-2084

Denso 475-2084 is a block-style A/C expansion valve that regulates refrigerant flow between the high- and low-pressure sides of the air conditioning system. It helps maintain proper evaporator performance in vehicles that need precise refrigerant control, including Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn Outlook applications.

The Denso New Expansion Valve line focuses on correct calibration for vehicle-specific HVAC systems. When the valve is out of spec, the evaporator can lose heat exchange efficiency or freeze, which can lead to poor cabin cooling and added system stress.

Key Features

• Block valve design for automotive A/C refrigerant control
• Separates suction and discharge sides of the HVAC system
• Supports stable evaporator operation by metering refrigerant flow
• OE-style replacement for front A/C service on listed vehicles
• Cross-references Four Seasons 39307 for the same application

Detailed Description

This Denso A/C expansion valve is built for front HVAC service on 2007-2012 GMC Acadia, 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, and 2007-2010 Saturn Outlook models. It is engineered to control liquid refrigerant entering the evaporator so the system can exchange heat correctly and maintain consistent vent temperatures. The part number 475-2084 is a direct-fit service option for these applications, and 475-2084 is the reference to use when matching the correct valve for your vehicle.

Denso’s expansion devices are developed from decades of A/C system engineering for automakers, with emphasis on calibration accuracy and system compatibility. For buyers searching for a front A/C expansion valve for Buick Enclave, Chevrolet Traverse, GMC Acadia, or Saturn Outlook, this part provides the specified block-valve configuration.

What It Helps Address

• Weak or inconsistent cabin cooling
• Evaporator freezing from incorrect refrigerant metering
• Poor heat exchange across the evaporator core
• A/C performance loss caused by a worn or incorrect expansion valve
• Front HVAC service needs on listed GM and Saturn models

Installation Notes and Tips

Verify the original valve style and vehicle application before installation. Replace the expansion valve during A/C system service only after the system has been properly recovered and evacuated, and confirm that the evaporator, compressor, and refrigerant lines are clean and free of contamination. Match the front position and block-valve configuration to the vehicle’s original setup.

Quality Assurance

Denso manufactures A/C components with application-specific calibration in mind, helping ensure the replacement valve matches the vehicle’s HVAC requirements. This part is intended for the listed fitments and should be selected by part number and vehicle application for accurate service.
