Usually you would put a wrench or ratchet on the crankshaft end nut and turn it. Note: if the engine is in running condition, ensure that the battery negative cable is disconnected as a safety precaution before doing this.
yes you can you have to use a socket on the crankshaft bolt and turn in the dirtection of the engine would run in
it is a regular bolt, turn right it tightens, turn left it loosens
Disconnect the battery, remove all spark plugs, and turn it over with a socket at the crankshaft.
Turn the bolt to the left to remove it.
See if you can turn the crankshaft by hand. If you can turn the crankshaft 360 degrees you probably have a starter motor that's failed. If the engine won't turn completely, it's probably a thrown rod.
With the bolt facing you, you should turn the bolt anti-clockwise to loosen it. It will be a right hand thread.
The crankshaft itself will turn the opposite way to the bolt.
Try taking out the spark plugs first, because turning the crank shaft with the plugs in creates pressure. Or it could be that there is a bent rod and the piston head is in the head wall.
Remove all the spark plugs and if it is a standard transmission vehicle, put it in neutral.
It is right hand thread. Turn counter clockwise to loosen.
The Engine can turn over with out gas. The started is engaged and turn the crankshaft, just as one would turn the engine over by hand. For sustained revolutions however, gas is needed to react in the engine chambers
Most crankshaft pully bolts on European engines turn anti clockwise to undo them.
