Denso New Expansion Valve 475-2049 is a block valve A/C expansion valve built to regulate refrigerant flow between the high- and low-pressure sides of the air conditioning system. For 2001-2009 Hyundai Santa Fe models, it supports proper evaporator operation and helps maintain stable cabin cooling performance.

Key Features

• Block valve design for A/C refrigerant metering
• Separates suction and discharge sides of the HVAC system
• Helps maintain correct evaporator heat exchange
• OE-style replacement for Hyundai Santa Fe applications
• Denso New Expansion Valve line for vehicle-specific A/C service

Detailed Description

The Denso New Expansion Valve line focuses on precise refrigerant control for automotive HVAC systems. Part number 475-2049 is engineered for 2001-2009 Hyundai Santa Fe models and is used to regulate liquid refrigerant entering the evaporator. When the valve calibration is correct, the evaporator can absorb heat as intended and the system can deliver consistent vent temperatures. This part cross-references Four Seasons 39087 for the same application.

What It Helps Address

• Weak or inconsistent A/C cooling in a Hyundai Santa Fe
• Evaporator icing caused by incorrect refrigerant metering
• Poor heat exchange across the evaporator core
• HVAC performance issues related to a worn or miscalibrated expansion valve
• Service replacement for 2001-2009 Hyundai Santa Fe A/C repair

Installation Notes and Tips

Verify the vehicle year and HVAC configuration before installation. Inspect the system for contamination, leaks, and compressor-related damage before replacing the valve. Proper evacuation, recharge, and system calibration are important after service so the A/C system can operate within specification. Confirm fitment for 2001-2009 Hyundai Santa Fe, N/A, before ordering.

Quality Assurance

Denso draws on decades of OE component and system engineering for automakers, and this expansion valve is built to match the application-specific requirements of the vehicle HVAC system. Part number 475-2049 is intended for direct replacement service on listed Hyundai Santa Fe models.
