Denso 475-2083 A/C Expansion Valve

Denso New Expansion Valve for Fusion, MKZ, Milan, and Zephyr

Denso 475-2083 is a block-style A/C expansion valve built to regulate refrigerant flow between the high- and low-pressure sides of the air conditioning system. For 2006-2009 Ford Fusion, 2007-2009 Lincoln MKZ, 2006-2009 Mercury Milan, and 2006 Lincoln Zephyr applications, this valve supports proper evaporator performance and stable cabin cooling.

The Denso New Expansion Valve line focuses on correct calibration for vehicle-specific HVAC systems. When the expansion valve is out of spec, the evaporator can lose heat-exchange efficiency or freeze, which can lead to poor A/C output and added system stress.

Key Features

• Part number: 475-2083
• Block valve design for automotive A/C flow control
• Separates suction and discharge sides of the HVAC system
• Helps maintain proper refrigerant metering through the evaporator
• Direct fit for select Ford, Lincoln, and Mercury models
• Cross-references Ford 6E5Z 19849-AA and Four Seasons 39306 for the same application

Product Details

This Denso A/C expansion valve is engineered for vehicles that require precise refrigerant control at the evaporator. It is a fitment-based replacement for 2006-2009 Ford Fusion, 2007-2009 Lincoln MKZ, 2006-2009 Mercury Milan, and 2006 Lincoln Zephyr. If you are searching for a 2006-2009 Ford Fusion A/C expansion valve or a 2007-2009 Lincoln MKZ HVAC flow restrictor, Denso 475-2083 matches the listed applications.

What It Helps Fix

• Weak or inconsistent cabin cooling
• Evaporator icing or freeze-up
• Improper refrigerant metering through the A/C system
• Reduced heat exchange at the evaporator
• HVAC performance issues tied to a worn or incorrect expansion valve

Installation Notes and Tips

Verify the vehicle’s year, make, and model against the listed fitment before installation. Inspect the surrounding A/C components for contamination, leaks, or damage before replacing the valve. Because this is a block valve application, confirm the original valve style and system configuration match the part number 475-2083.

Quality Assurance

Denso draws on decades of OE-level A/C engineering experience and supplies expansion devices calibrated for vehicle-specific HVAC systems. That focus on correct refrigerant control helps support reliable evaporator operation in the listed Ford Fusion, Lincoln MKZ, Mercury Milan, and Lincoln Zephyr applications.
