Description

Keep your engine running cool with the DENSO Auto Parts Radiator (P/N: 221-3420), a New OE Quality replacement and a direct-fit answer if you're searching for a Nissan Pathfinder radiator. It's cataloged for the 2000-2003 Infiniti QX4 and the 2001-2004 Nissan Pathfinder — see the Buyer's Guide tab for engine-level details.

Thin-tube aluminum core: Built with a thin-tube aluminum core and a superior fin pitch to move heat away from the coolant efficiently.
OE-quality standards: DENSO's radiator configurations, tanks, fin pitch, core dimensions and materials are made to meet OE manufacturers' rigid standards.
First Time Fit: Engineered with a First Time Fit philosophy, drawing on DENSO's OE experience supplying radiators to car makers worldwide.
Durability tested: Every DENSO radiator passes strict durability and function testing for reliable performance under demanding conditions.

The radiator is the heat exchanger that transfers engine heat to the passing airflow so coolant returns at the proper temperature. Signs it may need replacing include external coolant leaks from the core or tank seams, persistent overheating, or a clogged core. If a failed radiator is the cause of your cooling trouble, this DENSO unit replaces it.
