Detailed Description

This radiator is engineered for the 2003-2008 Infiniti FX35 and built to match original equipment form and function. OSC uses premium-grade materials, cadmium-plated tubes, and a die-cut gasket design to help maintain sealing integrity. The unit includes a plated transmission oil cooler and is assembled to factory specifications for a direct replacement on the FX35 cooling system. Part Number 2683 is also cross-referenced to Spectra Premium CU2683 for the same application.

Common Cooling System Issues

  • Coolant leaks from cracked tanks, seams, or aged seals
  • Overheating caused by restricted or damaged radiator flow
  • Transmission temperature concerns related to a failing cooler circuit
  • Reduced cooling efficiency from worn fins, tubes, or internal blockage
  • Fitment problems after replacing a damaged OE-style radiator

Installation Notes and Tips

Verify the radiator dimensions, inlet and outlet sizes, and cooler layout before installation on your Infiniti FX35. Transfer any required vehicle-specific components from the original assembly if applicable, and inspect hoses, clamps, and coolant condition at the same time. Proper system bleeding and a pressure check after installation help confirm a sealed repair.

Quality Assurance

OSC tests the radiator core before assembly and tests the completed unit again after assembly. Transmission and engine oil coolers are also tested prior to installation into the tank, and each radiator is pressure tested during production to help verify sealing and performance.
