How to service and repair a water pump on Mercury Grand Marquis?

The service and repair of the water pump requires the draining of coolant as the initial step. The next step requires you to unwind the bolts before taking out the belt. The next step includes taking off bolts and the water pump pulley before extracting the water pump from the system. Thoroughly clean the surface where the water pump will mount. Installation of the water pump housing within the engine requires absolute restraint in preventing any rotation because such movement damages the O-ring seal which leads to fluid leakage. You need to add a new O-ring seal which must get lubrication by proper engine coolant. The installation procedure ends with performing the steps in reverse order of removal.
