Denso 475-2103 A/C Expansion Valve

Denso 475-2103 A/C Expansion Valve

Denso New Expansion Valve 475-2103 regulates refrigerant flow through the evaporator to help maintain proper air conditioning performance. This block valve is built for specific Subaru applications, including Forester, Impreza, WRX, WRX STI, and XV Crosstrek models.

As an A/C flow restrictor, the expansion valve separates the low and high sides of the system so refrigerant can be metered correctly. Denso’s OE-focused engineering helps ensure the evaporator exchanges heat as intended in Subaru HVAC systems.

Key Features

• Block valve design for A/C refrigerant metering
• Controls flow between the high-pressure and low-pressure sides of the system
• Supports stable evaporator operation in Subaru HVAC systems
• OE-style replacement for select Subaru Forester, Impreza, WRX, WRX STI, and XV Crosstrek applications
• Part number 475-2103 for accurate ordering and fitment lookup

Installation Notes

Verify the vehicle build date and match the application exactly before installation. This Denso expansion valve 475-2103 is specified for select Subaru HVAC systems, so confirm the original valve style and system configuration before service. Proper evacuation, recharge, and leak checking are required after A/C component replacement.

Quality Assurance

Denso draws on decades of A/C system engineering for automakers, and this New Expansion Valve line is built to meet the calibration demands of the vehicle application. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
