Extruded Core Radiator a nd Electric Fan Kit

The Extruded Core Radiator and Electric Fan Kit from FLEX-A-LITE is engineered for serious engine builders and performance enthusiasts who demand superior cooling without mechanical complexity. Whether you're running a carbureted street engine, a modern EFI swap, or a high-output supercharged build, this kit eliminates parasitic horsepower loss from traditional belt-driven fans while delivering consistent, thermostat-controlled cooling under any driving condition. Built for custom hot rods, restorations, and upgraded daily drivers, this system transforms how air flows through your core and across your engine bay.

The extruded aluminum core maximizes surface area for efficient heat transfer, while the electric fan operates independently of engine speed, pulling full cooling capacity only when coolant temperature rises. This design eliminates the thermal load that mechanical fans impose on the crankshaft—a critical advantage at cruise where traditional fans waste 5–15 horsepower. The integrated thermostat control ensures the fan cycles on and off automatically, reducing fuel consumption and engine strain during light-load operation. Weighing 48 pounds and dimensioned at 40 x 8.5 x 51.5 inches, the assembly fits a wide range of engine compartments with careful installation planning and appropriate radiator hose routing.

This kit suits fuel-injected and naturally aspirated engines alike, making it ideal for vintage restorations receiving modern powerplants, LS swaps, SBC/BBC upgrades, and any custom build prioritizing efficiency and underhood aesthetics. Professional installers and experienced DIY mechanics appreciate FLEX-A-LITE's reputation for quality construction and reliable temperature regulation. Proper shrouding and clearance verification during installation ensure optimal airflow and fan performance, so confirm mounting points and hose diameter compatibility with your specific engine block and cooling system before final assembly.
