How do you change your water pump on a 93 Mazda mx3 4cylinder?

To change the water pump on a 1993 Mazda MX-3 with a 4-cylinder engine, first, disconnect the negative battery terminal and drain the coolant. Remove the drive belts, then take off the timing cover and loosen the timing belt tensioner to remove the timing belt. With the timing belt out of the way, unbolt the old water pump, clean the mating surfaces, and install the new pump with a new gasket. Reassemble in reverse order, ensuring proper alignment of the timing belt and tensioner.
