The 6.4L Powerstroke is a twin-turbocharged engine that makes real power — and produces real heat. These trucks are notorious for pushing cooling system limits under towing, tuning, or sustained high-load use, and the factory plastic-tank radiator was never built with much headroom. This 6-row extruded aluminum radiator is engineered specifically for the 2008–2010 F-250, F-350, F-450, and F-550 with the 6.4L Powerstroke. It mounts directly in the factory location with no cutting, no drilling, and no modification required.
Fluidyne eliminates that failure point entirely with a fully extruded aluminum core — a single-piece design with no brazed tube-to-header joints anywhere in the core. Every tank, fitting, and seam is finished with premium TIG welds throughout.
The 6-row core is the most aggressive configuration in the Fluidyne diesel lineup — and it’s here for a reason. The 6.4 runs harder than most platforms, and this unit is built to match. With a 37″ core and 2.75″ core depth, the heat rejection capacity is substantially higher than any conventional 3–4 row brazed-tube competitor. The fin pitch is optimized for the Super Duty’s factory shroud setup.
