Abstract
A radiator cap including a manually manipulable crown provides an auxiliary vacuum seal for sealing a potential vacuum leak path around a member penetrating through a central aperture of the crown. The member may be a rivet or stud which secures the crown, a bell housing and a discoid spring in an assembled condition. Alternatively, the member may be a vent pin connected to a manually manipulable safety lever. The auxiliary vacuum seal preferably takes the form of a resilient O-ring which surrounds the member and is sealingly interposed between the discoid spring, the member and the bell housing to seal a potential vacuum leak path between the member and the discoid spring.
