ABSTRACT:
A reservoir in which coolant is stored, is fluidly interposed between the downstream end of the condensor in which coolant vapor from the engine coolant jacket is condensed, and a coolant return pump which is responsive to a level sensor disposed in the coolant jacket, in a manner to form part of the cooling circuit of the system. The system further includes two temperature sensors, the first is disposed in the lower tank of the radiator and the other in the coolant jacket proximate the cylinder head. A device which modifies the pressure prevailing in the system is operated in response to one or both of the temperature sensors. This device can take the form of a cooling fan or an electromagnetic valve which controls one of a coolant jacket/atmosphere vent or a reservoir/atmosphere vent.
