Ive done it, you pull the belly pan, disconnect the large electrical connection on the lower driver side, take out the 4 large torx screws holding the entire shroud to the core support and lower out the bottom, then just swap the fan. I did have to slightly modify the small fan plug by trimming of part of the plug housing (was outside the sealed portion and didn't affect the locking so whatever.., was slightly different, but it works fine, that was a couple years ago now, all in all an easy task. Pro tip, slip a piece of cardboard between the radiator and fan shroud on removal and replacement so as to avoid bending any fins or worse damage.
I might have disconnected the passenger side inter cooler hose but I don't recall, it was a rather unmemorable experience, and I have not heard from it since.
