Detailed Description

This Denso radiator is designed to match OE radiator configuration, including tank design, fin pitch, core dimensions, and material selection. Denso supplies radiators to OE vehicle manufacturers worldwide, and this part reflects that manufacturing experience with a focus on fitment accuracy, cooling efficiency, and durability testing. The Denso 221-3416 is a direct-fit radiator for 2011-2017 Nissan Quest and 2009-2014 Nissan Murano, making it a practical replacement when the original cooling module shows signs of wear or leakage.

This part cross-references APDI 8013039 for the same application.

Vehicle Fitment

• Fits 2011-2017 Nissan Quest, N/A
• Fits 2009-2014 Nissan Murano, N/A

Common Issues This Radiator Addresses

• Coolant leaks from a cracked or corroded radiator
• Overheating caused by restricted coolant flow
• Transmission fluid temperature control concerns when the cooler circuit is part of the radiator
• Reduced cooling efficiency from aging core materials or damaged fins
• Fitment problems from using a radiator that does not match OE dimensions

Installation Notes and Quality Assurance

Verify core dimensions, inlet and outlet diameter, and transmission cooler routing before installation. Flush the cooling system, inspect hoses and clamps, and confirm the radiator mounts correctly in the factory location. Because this radiator includes a transmission oil cooler, check all cooler line connections for proper sealing during installation.

Denso radiators are built to OE standards and undergo durability and function testing before release. That quality process supports consistent performance in demanding driving conditions.
