Product Details

Denso’s New Receiver Drier line is built to factory standards for A/C service where moisture control and refrigerant management matter. This receiver drier helps separate liquid and vapor refrigerant while the desiccant package works to reduce moisture inside the system, helping protect internal A/C components from corrosion and premature wear. It is a direct-service HVAC component for vehicles that require this block union, female-female configuration.

Compatible With 1997 INFINITI I30, N/A; 1996 INFINITI I30, N/A; 1995-1996 Nissan 240SX, N/A; and 1995-1996 Nissan Maxima, N/A. This part cross-references Four Seasons 33573 for the same application. The Denso 478-2109 is also referenced in OE-style service listings for Infiniti and Nissan A/C repair work.

Common A/C Issues This Part Addresses

• Moisture contamination inside the air conditioning system

Installation Notes and Tips

Replace the receiver drier during major A/C service, especially when the system has been opened for repair. Verify the block union layout, female inlet and outlet fittings, and body dimensions before installation. Proper evacuation and recharge procedures are required after service to restore correct A/C operation.
