Built for OE-Style Cooling

OSC part number 1682 is a radiator assembly designed for Jeep TJ and Jeep Wrangler cooling systems where factory fit and consistent thermal control matter. The unit uses premium-grade aluminum construction with cadmium-plated tubes, a die-cut gasket for sealing, and factory-spec component placement to support proper fit in the engine bay. The integrated concentric transmission oil cooler is included for vehicles originally equipped with that setup, and the radiator is pressure tested during production to verify sealing and cooler integrity. This part cross-references APDI 8011015 for the same application.

Common Problems This Radiator Addresses

• Overheating from a restricted or aging radiator core
• Coolant leaks from worn tanks, seams, or gasket surfaces
• Transmission fluid temperature issues tied to a failing cooler circuit
• Reduced cooling efficiency in high-mileage Jeep TJ and Wrangler models
• Fitment problems caused by damaged or non-OE-style replacement radiators

Installation Notes and Tips

Confirm the vehicle uses the listed TOC threaded connections with barbed fittings before installation. The radiator is built as a drop-in replacement for the specified Jeep TJ and Wrangler applications, and the factory-style layout helps simplify alignment with existing mounting points and hose connections. Verify inlet and outlet sizes, cooler connection style, and overall core dimensions against the original unit before final assembly.

Quality Assurance

OSC radiators are produced with engineering updates aimed at improving durability and cooling performance over original designs. Part number 1682 is individually pressure tested, and the transmission and engine oil cooler circuits are checked during production stages to help confirm proper sealing and function before the unit leaves the factory.
