Denso 475-2076 A/C Expansion Valve

Denso A/C Expansion Valve for Sonata

Denso New Expansion Valve 475-2076 is a block valve for the air conditioning system, built to regulate refrigerant flow through the evaporator. For 2006-2009 Hyundai Sonata applications, it helps maintain the pressure split between the high and low sides of the A/C system so the evaporator can exchange heat correctly.

Denso’s expansion devices are engineered from decades of OE system experience, with calibration that matters for stable cooling performance. The Denso 475-2076 is a direct-fit style replacement for Hyundai Sonata A/C service where the original block valve has worn, restricted flow, or lost proper control.

Key Features

• Block valve design for automotive A/C refrigerant metering
• Separates suction and discharge sides of the system
• Supports proper evaporator heat exchange
• OE-style replacement for 2006-2009 Hyundai Sonata
• Cross-references Four Seasons 39264 and Global Parts Distributors LLC 3411831 for the same application
• Part number 475-2076 for ordering and catalog lookup

How This Expansion Valve Works

The expansion valve controls liquid refrigerant entering the evaporator, which is critical to stable cabin cooling. When calibration is off, the evaporator can lose efficiency or freeze, creating A/C performance problems and potential system damage. This Denso expansion valve is built for the Hyundai Sonata platform and is also identified by Hyundai part number 97626-3K000.

Common Problems It Can Address

• Weak or inconsistent A/C cooling in a 2006-2009 Hyundai Sonata
• Evaporator icing or freeze-up
• Improper refrigerant metering through the evaporator
• High-side and low-side pressure imbalance
• A/C performance loss after expansion valve wear or contamination

Installation Notes

Verify the vehicle year and HVAC configuration before installation. Replace the valve only after the system is properly recovered, evacuated, and inspected for contamination, leaks, and compressor debris. Clean mating surfaces and confirm correct refrigerant charge and system calibration after service. Fits 2006-2009 Hyundai Sonata, N/A.

Quality Assurance

Denso manufactures A/C components with OE-level engineering experience for vehicle-specific fit and refrigerant control. Part number 475-2076 is built for the listed Hyundai Sonata application and follows Denso’s expansion device calibration standards.
