Electric fan, wiring/relay kit, and rubber cooling flaps sold separately. When Space Is at A Premium, An Electric Cooling Fan Is a Must Engine driven fans have been around for more than a century and provide a simple solution to pulling ambient air through the vehicle’s radiator to reduce cooling system temperatures. Often used with a radiator mounted fan shroud They work well in stock engine/chassis environments but can often become a source of frustration when performing engine swaps or upgrading to thicker radiators to combat elevated temperatures in performance engine builds. Enter the electric cooling fan. The electric cooling fan, once a staple of engine swaps and race car builds has become the preferred OEM cooling fan of choice, and for several great reasons. They do not take away from engine horsepower, provide a much more compact cooling fan solution, and can be controlled in several ways (manual switch, thermal switch, modulated fan controller, etc.). The only drawback to an electric cooling fan has been in how to mount them to your radiator. Through the core mounts and universal brackets are the norm, but neither product is a secure fan mount and can damage your radiator’s core fins or tubes. Our new electric fan shroud provides a quick and secure way to mount an electric cooling fan while also providing an effective cooling solution by forcing air to be pulled through the whole radiator core and not just through the fan’s diameter area
