You Don't need to
You don't need to remove the fan clutch. In order to have more room, you remove the fan shrowd inside. There are couple of clips on top near the radiator that you need to remove. Once these clips are removed, the shrowd will come out. The shrowd is in two pieces. The inner piece turns then it will come out. The piece that is attached to the radiator will then come out.
You should have sufficient space to remove the water pump pulley and other essentials. As I mentioned before, be sure to belt tensioner bolt (it has a square insert, special socket) then loosen the belt with the vertical stem bolt. Then, you pull up on the belt and it will pull the belt adjuster to loosen the belt in order to remove it from the applicable pulleys.
Hope that's helped.
