Denso New Expansion Valve 475-2009

Denso 475-2009 is a block-style A/C expansion valve for vehicles that need precise refrigerant control at the evaporator. It separates the low and high sides of the air conditioning system and meters liquid refrigerant to help maintain proper cooling performance in Dodge Ram van, Plymouth Prowler, and other Chrysler-family applications.

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

Key Features

  • Block valve design for automotive A/C refrigerant flow control
  • OE-style replacement for front A/C and select auxiliary A/C applications
  • Helps regulate refrigerant delivery through the evaporator
  • Built for Chrysler, Dodge, and Plymouth fitments
  • Part number: 475-2009

Detailed Description

This Denso A/C expansion valve is used in systems that require accurate refrigerant metering to maintain stable evaporator performance. It is listed for applications including 1999-2003 Dodge Ram 1500 Van, Ram 2500 Van, and Ram 3500 Van, plus earlier Dodge B-series vans, Dakota, Ramcharger, and several Chrysler and Plymouth models. If you are replacing a worn or incorrect valve on a Dodge Ram 1500 Van front A/C system or a Plymouth Prowler A/C setup, 475-2009 provides the correct block-valve format for the application.

This part cross-references Four Seasons 38823 for the same application.

What It Helps Address

  • Weak or inconsistent cabin cooling
  • Evaporator icing or freeze-up
  • Incorrect refrigerant flow through the A/C system
  • Poor heat exchange at the evaporator
  • Replacement needs during A/C service on Chrysler, Dodge, and Plymouth vehicles

Installation Notes and Tips

Verify the vehicle’s A/C layout before ordering, especially front A/C versus auxiliary A/C configurations. Confirm the valve style and application notes against the original part, since calibration and system design must match for proper operation. Clean the surrounding A/C components during service and evacuate/recharge the system according to factory procedures after replacement.

Quality Assurance

Denso draws on decades of A/C system engineering for automakers, and this expansion valve is built to match the vehicle-specific calibration required for proper evaporator performance.
