How do you change the water pump on a 1991 Mazda miata?

To change the water pump on a 1991 Mazda Miata, first, disconnect the negative battery terminal and drain the coolant. Remove the drive belts, then detach the timing belt cover to access the water pump. Unbolt the old water pump, clean the mating surfaces, and install the new pump with a new gasket. Finally, reassemble the timing cover, reconnect the belts, refill the coolant, and reconnect the battery.
