How do I remove the radiator fan blade or the radiator fan blade clutch?
You need a fan clutch removal tool. You can look here http://www.bizrate.com/automotive-repair-tools/fan-clutch-removal-tool/ and see which one applies to your vehicle.

Some auto parts stores will lend the tool to you.
Thanks for the info. We tried removing the four bolts that appear to hold on the fan blade as that is what we are trying to replace, but it only loosened it and wouldn’t allow it to come free. I’m assuming the big nut is the one that actually holds on the fan blade.
