ABSTRACT:
A radiator cap is provided with safety venting character for use with a coolant recovery system. The cap is provided with lever means which compel safety venting of excess pressure in the radiator before the cap can be removed, the venting being effected automatically through a selectively movable valve that is moved to an open position by actuation of the lever means. The cap serves as part of a coolant recovery system, with the selectively movable valve also serving as the valve that automatically opens to permit siphoning of coolant back into the radiator during the cool-down portion of the coolant's heating and cooling cycle.
