Whereas belt-driven fans use up power from the engine to turn, electric fans do not, thus removing any unnecessary load and increasing both fuel economy and horsepower. In addition, you do not have to worry about an electric fan's slowing down at low RPM, as many belt-driven fans do, so you are guaranteed sufficient airflow regardless of the vehicle speed.

Before purchasing an electric fan, be sure to determine the CFM (cubic feet per minute) requirements for your engine. And remember, engines that have been modified or vehicles often used for towing may require additional CFM. There is no limit to the number of fans you can install, as long they all fit appropriately and are mounted on the same side of your radiator so that they do not cancel each other out.

Two types of turn-on sources are available for this fan. The Derale Lighted On/Off Switch for Electric Fans (D16740) allows for manual control of your fan so that you can choose when to turn it on and off. Thermostatic controls, on the other hand, send a signal to the fan, directing it to shut off when fluid temperatures reach an appropriate level, thus saving power. Once the temperature climbs again and additional cooling is needed, the fan is automatically turned back on. Thermostat switches can be single-stage with pre-set temperatures - D16735, D16738, D16739, D16720 and D16721 - or adjustable - D16778 and D16779.
