ABSTRACT:
In order to avoid the need to expose a coolant level control pump to hot and/or near boiling condensate the radiator is disposed at a level higher than the coolant jacket and gravity is used to return the condensate to the coolant jacket. A level sensor in the coolant jacket senses the coolant level and energizes the pump to induct cool coolant from a reservoir in the event that the level is found inadequate. The cooling circuit can be vented to the atmosphere in order to drop the excess coolant which is introduced into the system during non-use periods to the required level to speed engine warm-up following a cold engine start.
