Davies Craig mechanical thermal switches can be used with their thermatic fans and electric water pumps. The switches sense the coolant temperature after it passes through your engine block prior to entering the radiator—and automatically activate the thermatic fans at the set temperature when cooling is required. Davis Craig switches are available to control single or dual fans, and some models include an A/C relay, as well.
