The crankshaft nut shouldn't be the one holding the fan on! That is usually
a 1/4" bolt, that won't turn the engine! Don't break that bolt off- you'll
have to pull the water pump to remove it!
The Crankshaft nut is usually 3/4" or better- it is in the center of the
crankshaft pulley,(The lowest pulley, attached to the front of the
crankshaft) and once you put a big socket on it, and a breaker bar, you
should be able to turn the crank. And go clockwise to see if it is free. You
should see the valve train move within the first 1/4 turn.
I suggest you refer to a mechanic manual or shop manual for your car, and
look at the diagram of the crankshaft.
