Detailed Description

This OSC radiator is engineered to match original equipment form and function for the Nissan Pathfinder and Infiniti QX4. The radiator uses premium-grade aluminum construction with cadmium-plated tubes inside and out to help resist premature failure, while the die-cut gasket helps maintain a secure seal. OSC also builds in design enhancements such as improved fin density and a thicker core to address heat load in higher-mileage vehicles. Part Number 2055 is built for direct replacement use where the original vehicle setup calls for a downflow radiator with an integrated transmission cooler.

Common Problems This Radiator Can Address

• Coolant leaks from an aging or cracked radiator tank
• Transmission fluid temperature issues related to a failing cooler circuit
• Overheating caused by restricted or deteriorated radiator flow
• Loss of cooling efficiency from worn fins, tubes, or core damage
• Fitment issues when replacing a damaged factory radiator on a Nissan Pathfinder or Infiniti QX4

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet size, and transmission cooler routing before installation. This unit is designed for direct replacement in listed applications, including 2000 Infiniti QX4 built to 1/2000 and 1996-2000 Nissan Pathfinder, with 1997-1999 Infiniti QX4 also listed. Confirm the vehicle’s original cooling configuration matches the downflow layout and concentric transmission cooler setup. Part Number 2055 is intended for factory-style replacement where the original radiator uses an integrated transmission oil cooler.

Quality Assurance

OSC tests the radiator core before assembly, then tests the completed unit again, with transmission and engine oil cooler checks performed prior to tank installation. Each radiator is individually pressure tested and built to OE-style specifications for fit and function.
