Water pump for the 1996–1997 OBS 7.3L Power Stroke.
Weeping from the pump's weep hole, a bearing whine, or coolant loss with no visible external leak are the usual signs of a failing water pump. On a diesel that works hard, replacing it before it fails outright is cheaper than the alternative.
Note the year: this part covers 1996 onward. If your truck is a 1994 or 1995, confirm the correct pump before ordering — the OBS run is not a single fitment for every component.
