Denso 475-2107 A/C Expansion Valve

Denso New Expansion Valve 475-2107

Denso 475-2107 is a block-style A/C expansion valve for vehicles that need precise refrigerant control at the evaporator. It separates the low and high sides of the air conditioning system and regulates liquid refrigerant flow to help maintain stable cooling performance.

Built for direct-fit applications on select Toyota Prius, Prius V, Prius Plug-In, and Pontiac Vibe models, this Denso New Expansion Valve supports proper evaporator heat exchange when the original valve is restricted, inaccurate, or worn. The Denso expansion valve line is engineered for correct calibration so the A/C system can operate as intended.

Key Features

• Block valve design for automotive A/C refrigerant metering
• Controls liquid refrigerant flow through the evaporator
• Helps maintain separation between suction and discharge sides of the system
• OE-style replacement for select Toyota and Pontiac applications
• Part number 475-2107 for catalog and fitment lookup

Detailed Description

The expansion valve is a critical HVAC flow restrictor that directly affects evaporator performance. When calibration is off, the evaporator can lose heat-transfer efficiency or freeze, which can lead to poor cabin cooling and added strain on the system. Denso applies its A/C component engineering experience to supply the correct expansion device for the vehicle application. This part cross-references Toyota 88515-47040 and Four Seasons 39362 for the same application.

Compatible With 2010-2015 Toyota Prius, 2012-2017 Toyota Prius V, 2014-2015 Toyota Prius Plug-In, and 2009-2010 Pontiac Vibe. The 475-2107 part number is also useful when verifying replacement against OE references during A/C service.

What It Helps Address

• Weak or inconsistent cabin cooling
• Evaporator icing or freeze-up
• Incorrect refrigerant metering at the evaporator
• Poor heat exchange across the A/C system
• Replacement of a worn or inaccurate expansion valve

Installation Notes and Tips

Confirm the vehicle’s year, make, model, and A/C configuration before ordering. Inspect the surrounding HVAC components, refrigerant lines, and seals during service, and verify the system is properly evacuated and recharged after replacement. Match the valve type and OE reference before installation to ensure correct application.

Quality Assurance

Denso manufactures A/C components with application-specific calibration for automotive systems, and this New Expansion Valve line is built to support correct refrigerant control in the listed vehicles. Part number 475-2107 is cataloged for direct replacement use on the confirmed fitments above.
