The exact design of the water pump and it location vary slightly from engine to engine.
In some engines the water pump is driven by the engine's drive belt, while in others the pump is driven by the engine's timing belt. Since each vehicle is slightly different, you usually need to refer to the vehicle's service manual to determine the exact procedures needed to remove and replace the water pump; but I can help you :
1- drain the coolant fromthe system
2-if the pumhas radiator hose attached directly to it, loosen the hoseand remove it from the pump and / or any other hose attache to the water pump.
3- if the radiator fan is attached to the water pump loosen the retaining bolts with an appropriate wrench and remove the fan
4 -Loosen the tension on the belt and remove the belt from the engine.
5using an appropriate wrench remove the bolts that hold the pump housing to the engine, in many cases the lengh of the bolts varies pay attention to them.
5-After all bolts have been removed, remove the water pump from the engine.
6-When the old pum is off the negine, clean any leftover gasket material from the area
- compare the new water pump with the one you just remove from the engine, they must be same
7- reverse the disassembly steps to complete the job.
