A pump impeller assembly comprises a pump journal, an impeller fixed to one end of the pump journal, and a pulley fixed to the other end of the pump journal. The pump impeller assembly further comprises a pump bearing including an outer race surrounding the pump journal with the pump journal being adapted to rotate with respect to the outer race. The pump impeller assembly includes a support plate fixed to the outer race and lying in a radial plane with respect to the pump journal. The support plate has a plurality of locking tabs adjoining its peripheral edge. The locking tabs are circumferentially spaced apart from one another with respect to the pump journal. The locking tabs are adapted to interlock with locking lugs formed on the inner surface of a pump housing wherein the locking lugs are adjacent to a pulley opening in the pump housing through which the pulley extends and are circumferentially spaced apart from one another with respect to the pulley opening. The locking tabs are adapted so that the interlocking enables secure attachment of the support plate to the pump housing.

A vehicle coolant pump is improved with the addition of a channel shaped shield that surrounds the coolant weep holes. In addition to protecting the weep holes, expelled coolant is collected and allowed to evaporate before it can visibly pond. The channel also serves as a convenient point for the provision of wrenching flats when the pump housing is also used as a belt tension adjuster.
