Product Details

Denso’s New Receiver Drier line focuses on OE-style A/C service parts that help maintain refrigerant management and system cleanliness after major HVAC work. This receiver drier uses an aluminum housing with a block union configuration and female inlet and outlet fittings. The unit is specified for vehicles such as the 2003-2006 Subaru Baja, 2000-2003 Subaru Legacy, 2000-2003 Subaru Outback, 1998-1999 Nissan Sentra, 1997-1998 INFINITI QX4, 1997 INFINITI I30 from 06/1996, 1997 Nissan Maxima, and 1996-1997 Nissan Pathfinder. If you are replacing a receiver drier on a Subaru Outback, Nissan Pathfinder, or INFINITI QX4, 478-2050 matches the listed applications.

This part cross-references Four Seasons 83133 for the same application.

What It Helps Address

• Moisture contamination inside the A/C system
• Reduced cooling performance after A/C service
• Refrigerant flow irregularities in the HVAC circuit
• Corrosion-related wear inside A/C components
• Premature leaks caused by internal moisture exposure

Installation Notes

Replace the receiver drier during major A/C service, compressor replacement, or when the system has been opened to the atmosphere. Verify the block union layout, female inlet and outlet fittings, and body dimensions before installation. Proper evacuation and recharge procedures are required after service. Confirm vehicle-specific fitment for your Subaru Baja, Legacy, Outback, Nissan Sentra, Maxima, Pathfinder, or INFINITI application before ordering 478-2050.
