Denso 475-2101 A/C Expansion Valve

Denso A/C Expansion Valve for Mitsubishi

Denso New Expansion Valve 475-2101 is a block-style A/C expansion valve built to regulate refrigerant flow through the evaporator and keep the high- and low-side pressures separated. For Mitsubishi Eclipse, Endeavor, and Galant applications, correct calibration matters because improper refrigerant control can reduce heat exchange and contribute to evaporator freeze-up.

Denso’s expansion valve line reflects its OE-focused experience in automotive air conditioning systems. This part number, 475-2101, is a direct-fit replacement for select Mitsubishi vehicles and is also referenced by several OE and aftermarket numbers for the same application.

Key Features

• Block valve design for A/C refrigerant metering
• Helps regulate liquid refrigerant flow into the evaporator
• Supports proper separation of suction and discharge sides in the HVAC system
• OE-style replacement for select Mitsubishi Eclipse, Endeavor, and Galant models
• Cross-references Four Seasons 39332 and Global Parts Distributors LLC 3411388 for the same application

Detailed Description

The Denso 475-2101 expansion valve is engineered for vehicles that require precise refrigerant control at the evaporator inlet. When the valve calibration is correct, the A/C system can maintain stable cooling performance and avoid conditions that lead to poor heat transfer or evaporator icing. This makes it a practical replacement for Mitsubishi Eclipse, Mitsubishi Endeavor, and Mitsubishi Galant models that use a block valve configuration.

Compatible With 2006-2011 Mitsubishi Eclipse, N/A; 2004-2008 Mitsubishi Endeavor, N/A; 2010-2011 Mitsubishi Endeavor, N/A; and 2004-2011 Mitsubishi Galant, N/A. The part number 475-2101 is also associated with Mitsubishi OE references 7801A030, 7801A195, and MR958194.

What It Helps Address

• Weak or inconsistent cabin cooling
• Refrigerant flow control issues at the evaporator
• Evaporator freeze-up caused by incorrect metering
• A/C performance loss from a worn or inaccurate expansion valve
• Service replacement needs on Mitsubishi Eclipse, Endeavor, and Galant HVAC systems

Installation Notes and Tips

Verify the vehicle’s A/C system uses a block valve configuration before ordering. Match the OE reference and confirm the application by year and model, especially on Mitsubishi Eclipse, Endeavor, and Galant vehicles. After installation, the system should be evacuated and recharged according to factory service procedures, and the A/C system should be checked for leaks and proper vent temperature.

Quality Assurance

Denso manufactures A/C components with OE-level engineering focus, and its expansion devices are built to support correct refrigerant metering in automotive HVAC systems. Part number 475-2101 is a direct replacement for the listed applications and follows the brand’s OE-oriented product line standards.
