• Cooling loss from aging core fins or internal tube wear
• Poor fitment from a previous non-OE-style replacement
• Heat-related stress on higher-mileage Land Rover cooling systems

Installation Notes

Verify radiator dimensions, inlet and outlet size, and cooler configuration before installation. This unit does not include a cap, engine oil cooler, or transmission oil cooler. Use the vehicle’s factory mounting points and confirm all hose and connection surfaces are clean before assembly.

Quality Assurance

OSC radiators are pressure tested during production, with testing performed before cooler installation, after core testing, and again after final assembly. The design also incorporates engineering updates aimed at improving durability and cooling consistency in higher-mileage vehicles.
