Abstract
A small capacity pump continuously driven by a mechanical connection with the crankshaft or the like of the engine, is arranged to induct coolant from both the radiator wherein the coolant vapor is condensed to its liquid state and a liquid/vapor separator disposed in the vapor transfer conduit via which the coolant vapor is conveyed to the radiator from the coolant jacket. In order to maintain the cylinder head exhaust valves and ports immersed in a predetermined depth of liquid coolant a level sensor is disposed in the coolant jacket and the output used to open and close a valve fluidly interposed between the radiator and the pump. If required a second valve can be interposed between the pump and the separator and arranged to be closed when the first one is open.
