I was told by the local dealer you can get the fan off to replace the water pump by just pushing the radiator ahead.
Not working so well! Looked pretty straight forward. The only way I see to possibly moving it far enough, would be to take the oil cooler/condensor out, then maybe, otherwise remove the hood and mounting brackets?
The manual states to support hood with overhead device and then remove mounting brackets. Should be able to then tilt radiator forward to remove fan and shroud. I have never done it, so not sure. Not very many articulated 4x4 in this area.
