Detailed Description

OSC part number 13024 is a replacement radiator for the Toyota Highlander tow package application listed above. It uses a downflow configuration with integrated transmission oil cooling, making it a direct replacement choice for vehicles that rely on the factory-style cooling layout. The radiator is built with premium-grade aluminum core construction, plastic tanks, and cadmium-plated tubes inside and out to help resist premature failure. OSC also uses a die-cut gasket to support leak resistance and fits components to factory specifications during assembly. This radiator is designed to match OE form and function while maintaining the original look and fit of the cooling system.

This part cross-references Spectra Premium CU13024 for the same application.

Common Cooling Issues It May Address

• Coolant leaks from a cracked or aging radiator tank
• Reduced cooling performance under towing load
• Transmission heat buildup when the cooler circuit is worn or restricted
• Overheating caused by internal core deterioration
• Fitment problems from a damaged or non-OE replacement radiator

Installation Notes and Tips

Verify the vehicle is a 2008-2013 Toyota Highlander with tow package before installation. Confirm inlet and outlet hose sizes, cooler line routing, and mounting points against the original radiator. Flush the cooling system and inspect hoses, clamps, and cooler lines before installing the new unit. Because this radiator includes a transmission oil cooler, check for clean fluid flow and proper line connection during installation.

Quality Assurance

OSC tests complete radiators during production, including cooler testing before tank installation, core testing before assembly, and a final test after assembly. The design also incorporates engineering updates aimed at improving durability and cooling capacity for higher-mileage vehicles.
