OE-Style Cooling Replacement

This radiator is built to match original equipment form and function while using premium-grade aluminum components in the cooling assembly. OSC uses cadmium-plated tubes inside and out to help resist premature failure, along with a die-cut gasket for a tighter seal. Each unit is pressure tested during production and assembled to factory specifications for a direct-fit replacement on Jeep Commander and Jeep Grand Cherokee cooling systems.

Common Reasons for Replacement

• Coolant leaks from the radiator tank, core, or gasket area
• Overheating caused by restricted coolant flow or reduced heat transfer
• Cracked or aged plastic tanks on higher-mileage Jeep Grand Cherokee and Jeep Commander vehicles
• Cooling system service after radiator core damage or corrosion
• Replacement of a failed OE-style radiator with the correct inlet and outlet sizing

Installation Notes

Verify core dimensions, inlet and outlet sizes, and cooler configuration before installation. This radiator is a drop-in style replacement for the listed Jeep applications, and all necessary fittings or hardware are included in the unit. Inspect hoses, clamps, and surrounding cooling components during service to help prevent repeat leaks or overheating concerns.

Quality Assurance

OSC tests the radiator core before assembly and tests the completed unit again after assembly. Transmission and engine oil cooler circuits are also tested before installation into the tank when equipped. The design includes engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles.
