Description
If your Duramax runs hot while towing, hauling, or sitting in traffic with a trailer behind it, you know how frustrating it is to trust a radiator that feels like it’s always one hard pull away from leaking or failing. The Fluidyne 4 Row Extruded Tube Aluminum Radiator for the Chevy/GMC 2500HD and 3500HD 6.6L Duramax was built for diesel owners who want something stronger, longer-lasting, and better at handling real-world heat without worrying about weak factory-style construction. Instead of using thin brazed tubes, as in many traditional aftermarket aluminum radiators, Fluidyne uses a single-piece extruded aluminum core design that eliminates one of the most common failure points in standard radiators. That means added durability, improved cooling efficiency, and better confidence when your truck is working hard. Backed by over 30 years of performance cooling experience, including NASCAR applications, this radiator is designed to deliver excellent heat rejection while maintaining proper airflow and long-term reliability. Whether your truck is stock, tuned, towing heavy, or built for performance, this radiator is designed to help keep temperatures under control. This crossflow radiator features a natural aluminum finish, 4-row aluminum core, integrated transmission cooler, upper driver-side inlet, and lower passenger-side outlet. Core dimensions measure 33.5 inches long, 27.75 inches high, and 1.75 inches deep, while overall dimensions measure 44 inches long, 28.86 inches high, and 5.87 inches deep. It fits Chevy/GMC 2500HD and 3500HD models equipped with the 6.6L Duramax engine. Fan and radiator cap are not included. Each radiator ships in heavy-duty protective packaging to help ensure it arrives safely and ready to install.
