Product Details

The Denso New Receiver Drier 478-2021 is part of Denso’s First Time Fit line, which focuses on factory-style replacement components for A/C service. In the receiver-drier role, this unit helps manage liquid and vapor refrigerant flow while its desiccant package removes moisture from the system. That moisture control matters during major A/C repair because excess water can contribute to corrosion, internal wear, and refrigerant system leaks. This part cross-references Four Seasons 83084 for the same application.

Common A/C Issues It Can Help Address

• Weak or inconsistent cabin cooling on Jaguar XK8 and Jaguar XKR models
• Moisture contamination in the A/C system after compressor or line service
• Refrigerant flow instability that can cause surge-free operation concerns
• Corrosion-related wear inside the air conditioning circuit
• Leak-prone service conditions after major HVAC repairs

Installation Notes and Tips

• Fits 1997-2006 Jaguar XK8, N/A
• Fits 2000-2006 Jaguar XKR, N/A
• Replace the receiver drier during major A/C service or when the system has been opened to the atmosphere
• Verify female inlet and outlet connections before installation
• Confirm body dimensions and block union layout against the original part before assembly
