Fan Clutch

Yesterday I took the fan clutch out of the Dodge Ram 2500 diesel and brought it to the parts store. The nut part that threads onto the engine was very difficult to spin when cold, so I figured the clutch was bad. Comparing it to a new one at the store, it was just as difficult to turn.

I put the fan clutch back in the truck, started it up from cold, and stuck a rolled up piece of cardboard into it. It shredded it, not slowing down in the slightest.

Not sure how to test one of those fan clutches with a built in thermostat. Seems mine isn't working correctly and causes the engine to take a long time to warm up. Then again, the new part didn't turn freely either.

There is very little info online, mostly people showing the valve that the thermostat is on getting stuck, or the clutch fluid leaking out. Neither of which are my problem.
