To replace the water pump on a 1998 Chevy Lumina, first disconnect the negative battery cable and drain the coolant. Remove any components obstructing access, such as the serpentine belt and possibly the alternator. Unbolt the water pump from the engine block, clean the mating surfaces, and install the new pump with a new gasket. Finally, reassemble everything, refill the coolant, and check for leaks.
