The Denso New Expansion Valve line focuses on correct A/C metering for vehicle-specific applications. For Honda Civic owners searching for a 2006-2012 Honda Civic A/C expansion valve or Denso 475-2073 replacement, this part is matched to the vehicle platform and the system’s refrigerant control requirements.

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
• Vehicle-specific application for 2006-2012 Honda Civic
• Denso part number 475-2073 for catalog and service lookup
• Cross-reference: Honda 80221-SNA-A01

Detailed Description

This A/C expansion valve is used to control refrigerant delivery into the evaporator so the system can absorb heat efficiently. When calibration is off, the evaporator can lose heat-exchange performance or begin to freeze, which can lead to poor cabin cooling and added strain on the HVAC system. Denso 475-2073 is engineered for the Honda Civic platform and is listed for 2006-2012 Honda Civic models, making it a direct replacement choice for service work on the factory-style A/C system.

Compatible With 2006-2012 Honda Civic, N/A. This part cross-references Honda 80221-SNA-A01 for the same application.

What It Helps Address

• Weak or inconsistent cabin cooling
• Evaporator icing or freeze-up
• Incorrect refrigerant metering through the evaporator
• A/C performance loss caused by a worn expansion valve
• Service replacement needs on a 2006-2012 Honda Civic HVAC system

Installation Notes and Tips

Verify the vehicle year and HVAC configuration before installation. Replace the expansion valve only after confirming the rest of the A/C system is clean and properly evacuated, and inspect related components for contamination or restriction. Follow OEM service procedures for refrigerant recovery, evacuation, and recharge to protect system performance.

Quality Assurance

Denso draws on decades of A/C system engineering for global automakers, and this expansion valve is built to meet the application-specific calibration required for proper refrigerant control. Use the part number 475-2073 to confirm catalog match before ordering.
