Water pump 617.931 - 300GD - 12-13-2010

This morning could not start my 300GD with OM617.931 motor.I think battery is bad even I checked couple weeks ago was ok under load.Was cranking but no start.
But this isn’t problem im asking about.Right after trying to start it I see coolant leaking from under pump. I changed coolant for new before winter and mix it with water 50/50.
How hard is to replace water pump ? do I have to unbolt whole housing or just pump alone? Do I have to remove radiator …cooling fan ?
Thanks for any help.J
