With a factory computer controlled cooling fan it is often difficult to increase cooling system efficiency without having to hack the factory parts up and cobble things together to try and upgrade the cooling system’s electric cooling fan. At DeWitts we know Corvette owners are above that and want something that is a bolt-in solution that provides a solid cooling improvement as well. Our engineers have put together a great dual SPAL radiator fan upgrade that does just that; bolts right in and delivers a nearly 40 percent improvement in air flow.

Our dual fan kits for the C6 Corvette are designed to mount to our own aluminum Direct Fit® Pro Series performance radiators, both our standard height and “short” version radiators available for supercharged C6 Corvettes. These kits use a pair of 11-inch SPAL electric fans that pull 2,720 cfm through your radiator core to keep your temps in check. The included composite fan shrouds that house the two fans provide full radiator core coverage. Air pressure relief flaps are fitted to allow air to pass through at speed to prevent air stalling against the fan blades. These flaps close during low speed driving or when stopped to optimize air flow through the core by the fan’s blades.

All SPAL fans feature IP68 rated waterproof and sealed motors that are fully balanced with low-noise blade designs. This electric cooling fan kit is designed to bolt directly to your DeWitts Direct Fit® Pro Series or HP Series aluminum crossflow radiator with the included aluminum brackets and hardware. Your C6 Corvette’s fan wiring will need to be modified to connect this cooling fan package by removing the stock harness connector and splicing the two fan leads into your original wiring. The OE cooling fan module is retained, as you are only modifying the wiring from the module to the fan motor itself.
