So, I did it myself. Remove engine cover, remove V-belt, drain the coolant by removing top and bottom radiator pipes (bit messy). Disconnect the temperature sensor, remove water pump pulley (4X bolts). No specific tool is require. It is better if you loosen these 4X bolts before removing the belt. Disconnect the water pipe/s attached at the bottom of the water pump. Remove all the bolts. THE BOLTS ARE OF DIFFERENT SIZE, BOTH LENGTHS AND THREADING. IT IS VERY IMPORTANT THAT YOU MAKE A DIAGRAM AND PLACE THE BOLTS ACCORDINGLY. IF YOU FORGOT WHICH BOLT IS GOING WHERE - YOU ARE IN TROUBLE.
Remove old one, install new one by tightening bolts by hand first and then torquing appropriately. I dont have right torque numbers but I just randomly tightened.
Enjoy - you have saved over $1000 dollars.
