OE-Style Cooling Performance

Denso supplies radiators to OE vehicle manufacturers worldwide, and the 221-4415 reflects that OE experience in its tank design, fin pitch, core size, and material selection. This radiator is engineered for the 2013-2020 Nissan Pathfinder and 2013-2020 INFINITI QX60 coverage shown below, with fitment that also includes the 2013 INFINITI JX35 and select 2014-2016/2017 model-year notes. If you are replacing a worn radiator on a Nissan Pathfinder or INFINITI QX60, this Denso radiator provides the correct cooling-system layout for the listed vehicles.

This part cross-references Spectra Premium CU13348 and CSF 3680 for the same application.

What This Radiator Helps Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by reduced radiator efficiency
• Transmission temperature concerns when the cooler circuit is part of the failure
• Restricted cooling performance from internal clogging or corrosion
• Fitment issues from using a radiator with incorrect core dimensions or hose connections

Installation Notes and Fitment

Compatible With 2020 Nissan Pathfinder, radiator; 2013-2019 Nissan Pathfinder, radiator; 2014 Nissan Pathfinder, engine cooling; 2020 INFINITI QX60, radiator; 2015-2019 INFINITI QX60; 2016-2017 INFINITI QX60, from 01/2016 engine cooling; 2014 INFINITI QX60, to 04/2014; 2014 INFINITI QX60, to 04/2014 (engine cooling); 2013 INFINITI JX35, to 08/2012.

Verify hose diameter, mounting points, and transmission cooler line routing before installation. Confirm the vehicle’s build date and engine-cooling notes for 2014 and 2016-2017 applications to match the listed fitment exactly. Part number 221-4415 should be matched to the vehicle identification data before removal of the original radiator.
