Key Features

• Block valve design for controlled refrigerant metering at the evaporator
• Separates the low-side and high-side portions of the A/C system
• Supports proper evaporator heat exchange by maintaining correct refrigerant flow
• OE-style replacement for select Acura and Honda vehicles
• Denso part number 475-2022 for application matching and catalog lookup

Product Details

The Denso New Expansion Valve line focuses on accurate refrigerant control, which is critical to stable cabin cooling performance. When an expansion valve is out of calibration, the evaporator can lose efficiency or freeze, leading to poor A/C output and potential system damage. Denso applies its A/C system engineering experience to supply the correct expansion device for the vehicle application. This part cross-references Acura 80220-S6A-013 and Honda 80220-S6A-013 for the same application.

Compatible With 2004-2008 Acura TL, N/A; 2002-2006 Acura RSX, N/A; 2003-2007 Honda Accord, N/A; and 2002-2005 Honda Civic, N/A. Search terms such as Acura TL A/C expansion valve replacement, Honda Accord HVAC flow restrictor, and Honda Civic block valve replacement align with this application coverage. The part number 475-2022 is also useful when verifying the correct Denso replacement.

Common A/C Issues This Part Addresses

• Weak or inconsistent cabin cooling
• Evaporator icing or freeze-up
• Improper refrigerant metering through the evaporator
• Reduced A/C system efficiency
• System damage caused by incorrect expansion valve calibration

Installation Notes

Confirm the vehicle year, make, model, and A/C configuration before installation. Replace the expansion valve only after the system has been properly evacuated and serviced according to manufacturer procedures. Inspect related A/C components for contamination or restriction so the new valve can operate with correct refrigerant flow. Verify fitment against the vehicle listing for Acura TL, Acura RSX, Honda Accord, and Honda Civic before ordering.
