Product Details

CSF manufactures radiators to high-performance standards using validated cooling designs developed through laboratory wind-tunnel testing. Part Number 2833 follows an OE-style layout with plastic tanks and an aluminum core, making it a practical replacement for aging factory radiators on the Nissan Pathfinder and INFINITI QX4. The radiator is designed for vehicles that use a mini 13 psi cap and a down-flow configuration, with inlet and outlet placement matched to the original application.

This part cross-references APDI 8012459 and Spectra Premium CU2459 for the same application.

Common Cooling System Issues Addressed

  • Coolant leaks from cracked or deteriorated radiator tanks
  • Restricted cooling performance from a worn or clogged core
  • Overheating caused by reduced heat transfer efficiency
  • Fitment problems when replacing a damaged OE-style radiator
  • Transmission or engine cooling concerns tied to radiator wear

Installation Notes

Verify vehicle fitment by year, make, and model before installation. This radiator is specified for 2001-2004 Nissan Pathfinder and 2001-2003 INFINITI QX4 applications. Confirm the mini 13 psi cap requirement, hose orientation, and connection sizes before final assembly. Transfer any required vehicle-specific components from the original radiator if applicable to your setup.
