I had to replace the fan clutch on my motor becuase of temperature spikes and wobbling fan blades. Just be sure the clutch is what is wobbling and not the water pump shaft.

To start, disconnect the negative battery terminal and be sure the engine is cool. Be sure to leave the new fan clutch face down (nut up) so that the silicon fluid inside does not leak out. You need a 36mm fan wrench/open end or large adjustable wrench to remove the fan clutch from the wanter pump shaft.

Although I unbolted the fan shroud at this time, it will be easier to perform the clutch removal first, then unbolt the shroud in order to move it around to pull the fan completely out. With the shroud still in place, it will not move around and get in the way while trying to loosen the fan clutch nut. The fan shroud will NOT come out completely unless you remove the fan assembly and the the upper radiator hose. If/when you do unbolt the shroud, you need to disconnect the washer fluid bottle and coolant overflow reservoir and move them out of the way.
