A sealed accumulator is positioned at a location remote from the conventional pressurized liquid cooling system of an internal combustion engine. An overflow conduit communicates between a high point in the system and the accumulator. A make-up conduit communicates between the accumulator and a low point in the system. A normally closed pressure valve, opening in response to system pressure exceeding a predetermined value, is in series with the overflow conduit. In series with the make-up conduit, is a normally closed one-way check valve. Minimum and maximum pressures within the accumulator are regulated respective relief valves. Optionally, a vent valve is installed at a high point for escape of air as coolant is introduced into the system.
