Spectra Premium Radiator P/N:CU2339
Spectra Premium CU2459 radiator for the 2001-2004 Nissan Pathfinder V6 3.5L and other vehicles moves engine coolant through an aluminum core to shed heat. Its structure and design are built for the same durability and expectations as the OE radiator.
Coolant leaks, overheating or a temperature gauge that climbs can mean the radiator is worn, though a stuck thermostat or a weak water pump can show up in just the same way. Find out which one it is before you replace the radiator.
