How do you remove a 2001 Honda Civic crank shaft bolt?

Very simple... If you don't have the correct tools provided by Honda this is what I would do. Put the engine on TDC so all valves on #1 are closed. Rotate the engine clockwise about 30 degrees. Put a piece of rope down cylinder #1 spark plug hole. Rotate the counterclockwise until the piston pushes the rope to the top of the cylinder. All valves will be closed so there will be no damage. Put your breaker bar on the bolt and turn it off. Same for replacement. I do this trick all the time on engines.
