You will need to remove the timing belt cover and the timing belt to gain access to the water pump. This is not an easy job, and if you don't get the variable cam timing set correctly, or the timing belt installed correctly, you will have check engine light come on and at worst engine damage if the t-belt skips.
I strongly suggest you get a repair manual for this vehicle if your going to be doing your own work. You can get an online subscription to excellent information here:
