i cant fully answer this question but first you should purchase a repair manual. i know when relacing a water pump you must first disconect the negative connection from the battery, release the pressure and drain the coolant. next you must remove the radiator ,coolant fan and any other things that inhibit the removal of the water pump. remember to purchase the new water pump with a new gasket included. and you will need silicone to seal the water pump when replacing. that's basic hope it helps
