The viscous fan coupling will be easy to spin regardless of engine hot or cold. It's the rapid rotation of the coupling that makes the coupling go viscous and driving the fan.
It's way to late to comment but I've just noticed that your serpentine belt is the wrong side of your RH (looking at front of engine) idler wheel. Top tip, it's a smooth roller so goes on the smooth side of the belt. Top video for removing the fan though thanks!
Not quite.... I started out on the edge of Hull, moved down a touch, then started working near Sheffield..... Bit of a mixed bag vocally. Good call though!
