Abstract
A thermally reactive closure assembly for sealing a filler neck opening of a radiator and for controlling the fluid flow from the radiator through a passageway. The closure assembly includes a cap member and a vent valve associated with the passageway. The vent valve is movable between a normally opened position to a closed position sealing the passageway in response to a sufficient rate of fluid flow therethrough. The vent valve includes a spring operative to move the vent valve from the opened position to the closed position in response to increasing temperature of the cooling system environment.
