Detailed Product Overview
OSC Part Number 2459 is a replacement radiator designed around original equipment dimensions and cooling layout. The unit uses premium-grade tubes, fins, headers, and tanks, with cadmium-plated tubes inside and out to help resist premature failure. The radiator core is engineered for multi-fit use without changing the appearance or fit of the cooling system, and the transmission cooler is built into the assembly where originally equipped. This part cross-references Spectra Premium CU2459 for the same application.
Common Cooling System Issues
- Coolant leaks from a damaged or aging radiator tank or core
- Overheating caused by restricted coolant flow or reduced heat transfer
- Transmission temperature concerns related to a failing integrated cooler
- Fitment problems when replacing a radiator with the wrong core size or hose connection layout
- Premature radiator failure on higher-mileage Nissan Pathfinder and INFINITI QX4 vehicles

This radiator includes the transmission oil cooler and is built to factory specifications for the listed Nissan Pathfinder and INFINITI QX4 applications. Confirm the vehicle build date for the 2000 INFINITI QX4, since fitment begins from 1/2000. Part Number 2459 is a direct-fit replacement for the listed applications.
Quality Assurance
OSC tests the radiator core before assembly and retests the completed unit during production. The transmission and engine oil cooler circuits are also tested prior to installation into the tank, and the finished radiator is pressure tested to verify sealing and performance.
