A cooling system for an engine is divided into an inner circuit and an outer circuit, said inner circuit including a radiator, a cooling pump, a thermostat housing, an ejector pump, cooling channels arranged inside the engine and ducting connecting said components. The ejector pump is arranged to draw coolant from the outer system and deliver it to the inner system. The outer system includes an expansion tank, ducting interconnecting the expansion tank and the ejector pump and ducting interconnecting the inner circuit and the expansion tank. A one-way valve is placed in the ducting interconnecting the expansion tank and the inner circuit.
