ABSTRACT:
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.
