Product Details

This Global Parts radiator, part number 13681C, is built for the Toyota Tundra 5.7L platform from 2014 through 2021. The aluminum core and single-row layout are engineered to move heat away from the engine coolant efficiently, while the down-flow design matches the vehicle application. If you are replacing a leaking, clogged, or damaged radiator on a Toyota Tundra, 13681C provides the core cooling function needed to keep the engine operating at normal temperature.

This part cross-references Continental 13681 for the same application.

Common Issues This Radiator Can Address

• Coolant loss from a cracked or leaking radiator tank or core
• Engine temperature rise caused by restricted coolant flow
• Overheating from a damaged or corroded radiator assembly
• Cooling performance decline after internal blockage or fin damage
• Replacement needs after OEM radiator failure on Toyota Tundra models

Installation Notes and Tips

Verify radiator dimensions, inlet size, and cooler requirements before installation. This radiator does not include an engine oil cooler or transmission oil cooler, so confirm your vehicle’s original configuration matches those specifications. Flush the cooling system, inspect hoses and clamps, and refill with the correct coolant mixture after installation. For best results, check for trapped air and confirm proper fan operation once the system is back in service.
