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.

Thermal control cooling system vacuum valve

A locking, threaded gas cap for vehicle fuel tanks having threaded filler necks, the cap comprising a closure member threaded to engage and close the filler neck and an outer shell member mounted on the closure member for relative rotation to provide a hand grip. The closure member provides a plurality of abutments spaced peripherally about its axis while the shell member provides at least one yieldably movable drive finger extending radially outwardly into engagement with the abutments. The shell member provides a first stop for preventing movement of the drive finger out of engagement with the abutments when the shell member is rotated in one direction to thread the closure member onto the filler neck. The shell member provides a second stop having an operative position for preventing movement of the drive finger out of engagement with the abutments when the shell member is rotated in the opposite direction to remove the closure member. A key-operated lock is mounted in the shell member and connected to the second stop to move the second stop into and out of its operative position.
