Nice catch. In fact I had some cheap tools and did round one of those 10mm bolts off which led me to try and attack it by first (somehow) removing the fan and viscous clutch. But that has me stumped. So am I supposed to remove the fan first? Or take it all off in one big hunk?
In any case, thanks for the advice on the tools. I did stop by Lowes on the way home and bought a good set (supposedly) of USA made tools.
