Detailed Description

This receiver drier helps regulate liquid and vapor refrigerant movement while the desiccant package isolates moisture that can lead to corrosion inside the A/C system. That protection matters during compressor, condenser, or line service, when the system is opened and contamination risk increases. Denso 478-2032 is engineered for factory-style fit and performance on vehicles such as the Mercedes-Benz SL550 and S600, as well as Dodge Sprinter 2500 and Sprinter 3500 applications.

This part cross-references Mercedes-Benz 220 830 00 83 and Four Seasons 83114 for the same application.

What It Helps Address

• Moisture contamination in the A/C system
• Corrosion inside refrigerant components
• Reduced cooling performance after A/C service
• Unstable refrigerant flow through the system
• Premature wear caused by contaminated refrigerant circuits

Installation Notes and Tips

• Replace the receiver drier when major A/C service is performed or when the system has been opened.
• Verify fitment by year, make, and model before installation.
• Inspect related A/C components for contamination or wear before reassembly.
• Use correct service procedures for evacuation, charging, and leak checking after installation.

Quality Assurance

Denso manufactures this receiver drier to stringent factory standards as part of its First Time Fit component line. The design follows OE-style requirements for fit, function, and A/C system efficiency on confirmed Mercedes-Benz and Dodge Sprinter applications.
