its not attached to the fan should, its attached to the braket, thats bolted to the radiator support, that sits next to the fan/fan shroud. Ask Ford why they placed it there, probably because it was convient, or easy to access, if replacement was needed..
as far as relocating it, you can relocate it to the inner fender area, to clear up some free space. If your looking for info/pics, do a search for the threads with pics.
