Product Details

The Denso New Receiver Drier 478-2040 is built for A/C service where the receiver drier should be replaced after major system work. In Volkswagen Beetle and Volkswagen Jetta applications, this component helps manage liquid and vapor refrigerant flow while the desiccant package removes moisture that can lead to corrosion, leaks, and premature wear. Denso’s First Time Fit line is manufactured to factory standards for a direct-fit replacement approach.

This part cross-references Four Seasons 83053 for the same application.

What It Helps Address

• Moisture contamination inside the A/C system
• Corrosion-related damage to internal HVAC components
• Unstable refrigerant flow that can affect cooling performance
• Surging or inconsistent A/C operation after service
• Leak risk associated with worn receiver drier internals
