Product Details

Denso’s New Receiver Drier line is built to factory-level standards for HVAC service and replacement. In an automotive A/C system, the receiver drier helps regulate refrigerant flow and remove moisture that can lead to corrosion, reduced cooling performance, and premature internal wear. Part number 478-2037 is specified for 2007-2009 Chrysler Aspen and 2004-2009 Dodge Durango applications, making it a focused replacement for vehicles that need proper A/C system restoration.

This part cross-references Four Seasons 83231 for the same application.

What It Helps Address

• Weak or inconsistent A/C cooling
• Moisture contamination inside the refrigerant circuit
• Corrosion-related damage in A/C components
• Reduced system efficiency after major A/C service
• Surge-prone refrigerant flow in the HVAC system

Installation Notes and Tips

Replace the receiver drier during major A/C service, especially when the system has been opened for repair. Verify female inlet and outlet connections, block union style, and body dimensions before installation. For Chrysler Aspen and Dodge Durango service, confirm the vehicle year and A/C configuration against the listed fitment before ordering 478-2037.
