Water Pump: Service and Repair

]All water pumps have a sealed bearing integral with the water pump shaft. The bearing requires no lubrication. A bleed hole in the pump housing allows water that may leak past the seal to be thrown out by the slinger. This is not a lubrication hole. If the pump is damaged and requires repair, replace it with a new pump or a rebuilt one.
