How to remove a water pump
Locate water pump.. It's where the bottom radiator hose goes from the radiator. Remove any brackets or parts that are in your way. Remove water pump! Reverse procedure for installation.
You have to remove the fan clutch from the water pump shaft and lift the shroud, fan and clutch all out together.
remove two bolts in the center radiator support which let the radiator move forward an inch or so, loosen the fan from the clutch for a little more wiggle room to get it out. The shroud will have rubber splash shields hooked to the lower sides too, so be sure to unhook them or you will tear out the holes in the rubber shields.The fan clutch has to come off anyway because it's attached to the water pump. You don't need to remove the fan shroud. Just take out two bolts on the fan clutch and loosen the other two so you can push the clutch back a little (DON'T let the fan clutch fall). Then remove the water pump. It's a little tight, but much easier than removing the fan shroud.the only specialty tool that you will need is the water pumpt "grab" tool and the fan clutch wrench. These two items come together in one kit that you can rent from the Auto Parts store.
The "grab" tool holds the water pumpt pully firmly while you rotate the fan clutch retainer using the fan clutch wrench.
DO NOT attempt to use a break over bar or some other home-grown tool to hold the water pump pully while attempting to break the fan clutch free - you will mess up the heads of the four retainer bolts holding the pully to the water pump face.
this will help.thanks.
