ABSTRACT:
A method for preventing undesirable heat losses in a cooling system for liquid-cooled vehicular internal-combustion engines by affecting the flow at the connections of the lines to and from the header tank of the cooling system by measures commonly practiced in flow engineering such that the pressure will be the same at the inlet and the outlet of the header tank, so that with the thermostat closed no coolant is allowed to flow through the header tank and on through the radiator. With a cooling system having an engine vent line which connects to the header tank this method produces, by affecting the flow in the engine vent area and with the engine running and the thermostat closed, a pressure at the connecting point of the vent line for engine venting which is equal to that prevailing at the entry of the vent line to the header tank.
