Heres what I do;
-remove fan and fan shroud
-loosen water pump pulley bolts just a hair
-remove belts
-remove water pump pulley
-remove crank pulley (make sure metal pin on crank goes into correct hole on pulley when re-installing pulley)
-remove the 4 coolant hoses
-remove thermostat from water pump if not replacing thermostat, even tho i recommend replacing it also since youre in there.
-disconnect plugs
-remove water pump
-apply silicone spray to the small oring on pump and black tube.
-reverse for install.
-bleed cooling system

It helps to have a Bentley manual when you are DIYing. Even if you know how to do a repair you still NEED the torque spec of the fasteners you are removing/installing! If you find a DIY with torque specs you are relying on data that can possibly be incorrect, I doubt the DIY poster will step up and pay for additional repair costs due to stripped threads/damaged and broken parts due to fat fingered typing or incorrect info. Get the BMW bible and proceed.

The author, Hayaku, did an outstanding job on this write-up and is a skilled "wrench". He helped me change the water pump in my 3.0. Luckily I don't live too far from him.
