  • Vehicle engine cooling radiator
    Patent number: 6056045
    Abstract: A rib is provided around a hose connecting portion which is projected from an upper tank of a radiator. A cooling water which is leaked from a fitting portion between a hose and a hose connecting portion is guided to a predetermined position by the rib. As a result, such an event can be eliminated that the leakage cooling water drops downward and then attaches to a caulking portion between the upper tank and a core portion and thus such water is misconceived for a leakage water generated from the caulking portion.
