Denso 475-2047 A/C Expansion Valve

Denso New Expansion Valve for Nissan and Infiniti

The Denso 475-2047 is a block-style A/C expansion valve built to regulate refrigerant flow between the high- and low-pressure sides of the air conditioning system. For 2003-2009 Nissan 350Z and select 2003-2008 INFINITI FX35, FX45, and 2003-2007 INFINITI G35 applications, this valve supports proper evaporator performance and stable cabin cooling.

Denso’s New Expansion Valve line focuses on correct calibration for the vehicle’s HVAC system. When the expansion valve is out of spec, the evaporator can lose heat-transfer efficiency or freeze, which can lead to additional A/C system damage. Part number 475-2047 is built for direct replacement use in the listed applications.

Key Features

• Block valve design for automotive A/C flow control
• Regulates liquid refrigerant entering the evaporator
• Supports proper separation of suction and discharge sides
• OE-focused Denso New Expansion Valve product line
• Cross-references Datsun/Nissan 92200-AL500 and Four Seasons 39076

Detailed Description

Denso 475-2047 is an A/C expansion valve for vehicles that require precise refrigerant metering at the evaporator. This component is critical to HVAC performance because it controls how much liquid refrigerant is allowed through the system, helping the evaporator absorb heat efficiently. In the 2003-2009 Nissan 350Z and the listed INFINITI FX35, FX45, and G35 applications, correct valve calibration is essential for consistent vent temperatures and reliable system operation.

This part cross-references Datsun/Nissan 92200-AL500 and Four Seasons 39076 for the same application. If you are searching for a Denso 475-2047 expansion valve for Nissan 350Z or INFINITI G35 HVAC repair, this part matches the listed vehicle coverage.

What It Helps Address

• Weak or inconsistent A/C cooling
• Evaporator icing or freeze-up
• Improper refrigerant flow through the evaporator
• Poor heat exchange in the HVAC system
• System damage caused by incorrect expansion valve calibration

Installation Notes and Tips

Verify the vehicle’s A/C diagnosis before replacement and confirm the part number against the original valve. Clean the system as needed, inspect related seals and lines, and evacuate and recharge the refrigerant system according to factory service procedures after installation. Confirm fitment for the exact year and model before ordering.
