Detailed Description

OSC Part Number 2075 is a replacement radiator designed for vehicles that need OE-style cooling performance and a direct-fit layout. The radiator is built with premium materials, including cadmium-plated tubes and a die-cut gasket to help maintain sealing integrity. The integrated transmission oil cooler uses a concentric design, and the unit is engineered to match original cooler design where equipped. For Nissan Pathfinder and INFINITI QX4 cooling system service, this radiator supports a straightforward replacement path without changing the original appearance or mounting style.

This part cross-references Spectra Premium CU2075 for the same application.

What This Radiator Helps Address

• Coolant leaks from a damaged or aging radiator core, tank, or gasket
• Overheating caused by restricted coolant flow or reduced heat transfer
• Transmission fluid temperature concerns when the original cooler is worn or failing
• Cracked plastic tanks or weakened radiator seams on higher-mileage vehicles
• Cooling performance loss on 1996-2000 Nissan Pathfinder and 1997-2000 INFINITI QX4 models

Installation Notes and Tips

Verify the vehicle’s year, model, and radiator configuration before installation. This radiator is a downflow design with a concentric transmission cooler, so confirm hose routing, inlet and outlet sizing, and mounting points against the original unit. Flush the cooling system, inspect hoses and clamps, and check transmission cooler lines for contamination before installing the replacement radiator.

Part Number 2075 is listed for 2000 INFINITI QX4, 1997-1999 INFINITI QX4, 1996-2000 Nissan Pathfinder, and 1996-1997 Nissan Pathfinder applications. Use the fitment notes for the 2000 INFINITI QX4 to confirm the early-production cutoff.

Quality Assurance

OSC tests the radiator core before assembly and retests the completed unit after assembly, with additional testing of the transmission and engine oil coolers prior to installation into the tank. The design also incorporates engineering updates aimed at addressing common original-design failure points and improving durability in higher-mileage service.
