ABSTRACT:
The level of coolant in the coolant jacket of an "evaporation cooled" engine (wherein the coolant is boiled off in place of being forcefully circulated) is detected by a plurality of level sensors so that even though the attitude of the coolant level changes due to a change in orientation of the engine or the like, as long as one of the sensors is immersed in the coolant, the pump which recirculates condensed coolant from a radiator is not energized. An additional low level sensor is used to lower the level of the coolant to an predetermined low level to promote rapid engine warm-up during cold engine starts.
