CJ Clayton, national sales manager for Maradyne High Performance Fans, has over 25 years of automotive industry experience and a passion for performance, from dragsters and hot rods to off-road vehicles. An electric fan and engine cooling expert, he has outlined some points to consider about the benefits and selection of an electric cooling fan.
Electric cooling fans can deliver a number of important benefits to a wide range of vehicles and driving situations. Optimizing the air movement across the fins of the radiator is essential to prevent overheating, a task that electric fans can often handle better than engine-driven fans.
If your vehicle was always in constant motion, you probably wouldn’t even need a fan. Moving down the road would create enough ambient air flow and would be enough to cool down the car’s coolant. However, when your car stops at lights and occasionally gets stuck in traffic, the air flow assist that cooling fans provide becomes a necessity.
A key advantage of electric fans is increased engine cooling and improved air conditioning cooling at idle, when it is most needed. In addition, replacing an engine-driven fan can increase horsepower and improve fuel economy as the engine drag from turning the fan is eliminated. Electric cooling fans operate like any other electrically-powered accessory on the car. Its source of energy is the electrical system of the vehicle as supplied through the battery in conjunction with the alternator.
