The 6.4L Powerstroke is known for making serious heat, especially when towing, hauling, or running tuned. If you’ve dealt with rising coolant temps or weak factory-style radiator designs, upgrading your cooling system can make a huge difference in how confidently your truck performs day to day. The Fluidyne 6 Row Extruded Tube Aluminum Radiator for the Ford F250, F350, F450, F550 6.4L Powerstroke was built for diesel owners who want stronger construction, dependable cooling, and long-term reliability without constantly worrying about leaks or radiator failure.
Unlike many traditional aftermarket radiators that use thin brazed tube construction, Fluidyne uses a single-piece extruded aluminum core designed to eliminate one of the most common failure points found in standard radiator designs. This heavy-duty construction helps improve durability, cooling efficiency, and heat rejection under demanding conditions. Backed by over 30 years of performance cooling experience, including NASCAR-proven technology, this radiator is engineered to help keep coolant temperatures stable whether your truck is towing heavy, daily driving, or built for performance use. Its proprietary fin design improves airflow and heat dissipation while the integrated transmission cooler helps support complete cooling system performance.
This crossflow-style radiator features a natural aluminum finish, 6-row aluminum core, upper driver-side inlet, middle passenger-side outlet, and built-in transmission cooler. Core dimensions measure 37 inches long, 27.5 inches high, and 2.75 inches deep, while overall dimensions measure 43.25 inches long, 28.78 inches high, and 7.87 inches deep. It fits Ford F250, F350, F450, F550 models equipped with the 6.4L Powerstroke engine. Fan and radiator cap are not included. Each radiator ships in reinforced packaging with high-density foam to help ensure it arrives safely and ready to install.
