Denso 475-2081 A/C Expansion Valve - Front

Denso New Expansion Valve 475-2081

Denso 475-2081 is a block-style A/C expansion valve for vehicles that need precise refrigerant control across the evaporator. It separates the low and high sides of the air conditioning system and meters liquid refrigerant to help maintain stable cooling performance.

Compatible with select Nissan and INFINITI applications, including Nissan Altima, Sentra, 370Z, GT-R, and NV-series vans, this expansion valve is built for direct-fit service on the listed vehicles. The Denso New Expansion Valve line focuses on correct calibration for the application, which is critical to proper evaporator heat exchange.

Key Features

• Block valve design for A/C refrigerant flow control
• OE-style replacement for select Nissan and INFINITI vehicles
• Helps regulate refrigerant delivery through the evaporator
• Supports stable cabin cooling performance when the original valve is worn or restricted
• Part number: 475-2081

Product Details

Denso expansion devices are engineered for the demands of modern automotive HVAC systems. This A/C expansion valve meters refrigerant into the evaporator so the system can absorb heat efficiently without overfeeding the core. Correct calibration matters: if the valve is out of spec, the evaporator can lose heat-transfer efficiency or freeze, which can lead to additional A/C system damage. This part cross-references Four Seasons 39292 for the same application.

What It Helps Address

• Weak or inconsistent A/C cooling
• Evaporator icing or freeze-up
• Restricted refrigerant flow through the evaporator
• Incorrect suction and discharge side separation
• HVAC performance loss on Nissan Altima, Sentra, and INFINITI G37 applications

Installation Notes

• Verify the vehicle’s A/C system configuration before ordering.
• Replace the expansion valve when servicing a contaminated or restricted system.
• Inspect seals, lines, and the evaporator area for debris or damage during installation.
• Evacuate and recharge the system according to factory service procedures after installation.

Quality Assurance

Denso draws on decades of A/C system engineering experience supplying components to automakers. The 475-2081 is built to match the application-specific calibration needed for proper HVAC operation on listed Nissan and INFINITI models.
