To change the water pump on a 1993 Chrysler New Yorker, first disconnect the negative battery cable and drain the coolant from the radiator. Remove any components obstructing access to the water pump, such as the serpentine belt and, if necessary, the timing cover. Unbolt the old water pump from the engine block, clean the mounting surface, and install the new pump with a new gasket. Finally, reassemble the components, refill the coolant, and reconnect the battery.
