Abstract
A cooling system closure includes a closure apparatus adapted to mount on a cooling system and formed to include a flow passage arranged to receive fluid discharged from the cooling system and a relief valve positioned to move between an opened position permitting fluid to flow through the flow passage and a closed position blocking the flow of fluid through the flow passage. The relief valve includes a temperature-activated element moving to a first position when heated to a first predetermined temperature to urge the relief valve to the closed position and a second position when cooled below a second predetermined temperature to permit the relief valve to move to the opened position.
