The Derale 16759 is an adjustable electric fan control kit that lets you set the fan turn-on temperature anywhere from 150°F to 240°F, with turn-off preset 10 degrees below the turn-on point. It controls up to two fans at a total maximum draw of 25 amps through a heavy-duty 40/60 amp relay. A push-in radiator fin probe with thermostat sensor reads coolant temperature, and an A/C override circuit runs the fans when the air conditioning is on.
