Abstract
Abstract An inlet couples a duct system to a point in the cooling system of a liquid-cooled engine. A liquid differential adjusting device in the duct system adjusts for the type of liquid in the cooling system. A thermometer in the duct system detects and indicates the temperature of the liquid in the system. A pressure gage in the duct system detects and indicates the pressure of the liquid in the system. An outlet couples the duct system to another point in the cooling system of the engine.
