Reliable Cooling for Heavy-Duty Demands. The Radiator is a direct-fit replacement engineered to restore and maintain proper cooling performance in your Sierra 2500 HD's 6.6L Duramax engine. Designed to meet or exceed OEM standards, the radiator efficiently dissipates heat to prevent overheating, especially under heavy towing or high-load conditions. The radiator is a vital upgrade for preserving engine health and overall vehicle reliability.
Construction and Appearance. Built with a high-efficiency aluminum core, the radiator is available with either plastic tanks or a full aluminum design depending on the brand. Each unit is crafted to handle the thermal loads of a high-output diesel engine, offering enhanced heat transfer and corrosion resistance. It fits seamlessly in place of the factory unit using existing mounts and hose connections.
Installation. Installation is moderately difficult and may require draining coolant and removing other front-end components for access. While compatible with factory hoses and mounting points, professional installation is recommended for best results and proper system bleeding.
Warranty. The product is backed by a limited lifetime warranty, providing peace of mind and long-term coverage.
Application. The Radiator fits 2011-2016 6.6L Duramax Sierra 2500 HD.
