Denso 475-2102 A/C Expansion Valve

Denso A/C Expansion Valve for Nissan

Denso New Expansion Valve 475-2102 is a block-style A/C expansion valve that regulates refrigerant flow through the evaporator. It separates the low and high sides of the air conditioning system so the evaporator can exchange heat correctly in Nissan Murano and Nissan Sentra applications.

Key Features

• Block valve design for controlled refrigerant metering
• Helps maintain proper evaporator performance in the A/C system
• OE-focused Denso expansion device for vehicle-specific fitment
• Direct replacement for select Nissan applications
• Part number: 475-2102

Product Details

Denso’s New Expansion Valve line is built around precise refrigerant control for automotive HVAC systems. This expansion valve is used to manage liquid refrigerant entering the evaporator, which is critical for stable cooling performance. When the valve calibration is off, the evaporator can lose heat-transfer efficiency or freeze, leading to A/C performance problems and potential system damage. This part cross-references Four Seasons 39346 for the same application. Compatible with 2009-2011 Nissan Murano and 2002-2006 Nissan Sentra, this Denso 475-2102 expansion valve supports the factory-style HVAC layout used in these vehicles.

Common Issues This Part May Address

• Weak or inconsistent cabin cooling
• Evaporator icing or freeze-up
• Improper refrigerant flow through the A/C system
• Loss of evaporator heat exchange efficiency
• HVAC performance issues tied to a worn or miscalibrated expansion valve

Installation Notes and Tips

Verify the vehicle’s A/C diagnosis before replacement and confirm the valve style matches the original block valve configuration. Inspect the evaporator, lines, and seals for contamination or damage during service, and evacuate and recharge the system according to factory procedures after installation. Confirm fitment by year, make, and model before ordering the Denso 475-2102.

Quality Assurance

Denso draws on decades of A/C system engineering for global automakers, with expansion devices built to meet vehicle-specific calibration needs. That OE-level engineering focus helps ensure the valve is selected for the correct application and refrigerant control requirements.
