Change a water pump on a 1995 T100 SR5 two wheel dr. 3.4 engine?

To change the water pump on a 1995 Toyota T100 SR5 with a 3.4L engine, first disconnect the battery and drain the coolant. Remove the serpentine belt, then take off the timing cover to access the water pump. Remove the bolts securing the pump, clean the mounting surface, and install the new pump with a new gasket. Reassemble everything in reverse order, refill the coolant, and check for leaks.
