Abstract
A radiator includes a neck including a pair of openings and a plurality of threads configured to engage a plurality of threads disposed within a radiator cap. The neck threads and the radiator cap threads each include a thread stop and a clearance and permit the radiator cap to rotate to a fully closed position. The clearance permits the radiator cap to move in an axial direction when not in the fully closed position without rotating from the fully closed position. The thread stops are configured prevent the radiator cap from rotating after moving axially.
