Denso 475-2074 A/C Expansion Valve

Denso A/C Expansion Valve for Honda Civic

Denso New Expansion Valve 475-2074 is an OE-style A/C flow restrictor built to regulate refrigerant flow through the evaporator. For 2006-2012 Honda Civic applications, this block valve helps maintain proper separation between the low and high sides of the air conditioning system so the evaporator can exchange heat correctly.

The Denso New Expansion Valve line focuses on correct calibration and vehicle-specific A/C control. When the valve is out of spec, the system can lose cooling performance or the evaporator can freeze, which can lead to additional A/C damage. Part number 475-2074 is built for direct replacement use on the Honda Civic platform listed below.

Key Features

• Block valve design for automotive A/C refrigerant metering
• Regulates liquid refrigerant flow into the evaporator
• Supports proper low-side and high-side system separation
• OE-style replacement for 2006-2012 Honda Civic A/C service
• Denso New Expansion Valve product line for vehicle-specific fitment

Detailed Description

Compatible With 2006-2012 Honda Civic, N/A. Denso 475-2074 is an A/C expansion valve used to control refrigerant delivery at the evaporator inlet. This function is critical to stable cabin cooling because the valve must meter flow accurately for the system to absorb heat without starving the evaporator or allowing it to freeze. This part cross-references Honda 80221-SVA-A01 for the same application.

Common A/C Problems This Part Can Address

• Weak or inconsistent cabin cooling
• Evaporator icing or freeze-up
• Incorrect refrigerant flow through the evaporator
• High-side and low-side pressure imbalance caused by a worn valve
• A/C performance loss on Honda Civic models

Installation Notes and Tips

Verify the vehicle year, model, and A/C configuration before installation. Replace the expansion valve only after confirming the system is clean and free of contamination, and inspect related A/C components for wear or blockage. Proper evacuation and recharge procedures are required after service to restore correct system operation. Confirm the part number 475-2074 against the original component before installation.

Quality Assurance

Denso engineers A/C components with application-specific calibration for automotive systems, and this expansion valve is built to match the listed Honda Civic fitment. Use the confirmed vehicle coverage and OE cross-reference to verify selection before service.
