I just removed the fan assembly, and I also removed the belt. It's not the viscous clutch that has play, but the whole pulley instead! I just saw an exploded diagram using a parts catalog, and it seems that it has an idler pulley. Could it be that this is destroyed, and if so, is it easy to replace? I still haven't removed the viscous clutch since the 8mm bolt is seized, and I have to lube it for a while.
