ABSTRACT:
A water seal coolant wick comprises a ring of absorbent material, such as felt, disposed in the drain cavity between the inner radial face of a water pump seal in a water pump and the bearing housing so that the wick is disposed in the leakage path between the seal and the drain cavity weep hole, the wick preferably completely filling the drain cavity and acting to absorb insignificant weepage from the seal and keep it within the housing, out of sight, while allowing substantial leakage, which would be indicative of pump failure, to flow out of the weep hole.
