ABSTRACT:
A pre-heater for internal combustion engines, especially adapted for use in cold climates while a vehicle is being stored, parked, or otherwise idle. The heater has a base member that is adapted to be secured in an opening of the engine block, and an electric heating element carried by the base member and exposed to the interior area of the block so as to be in contact with the coolant thereof. Electric terminals carried by the base member are connected to the heating element to effect energization thereof. An electric cable is also provided, having a plug detachable from the base member. The plug has mating terminals cooperable with the electric terminals of the base member to establish an electrical circuit through the heating element. A heat-responsive sensor device is carried by the plug, and monitors the temperature of the base member and heating element in order to effect an automatic control of the energization of the latter.
