HELP! PLEASE! SOMEONE! Which way to undo crankshaft nut on my 1998 Grand Move 1500cc? The HE -EG engine also fits some Charades, I believe. Any significance to little tag lying flat against pulley, behind nut. It has a little triangle or arrow head on it, but this points "outwards" rather than to one side or the other. I don,t want to damage it in finding out if it is a locking device! Trying to replace timing belt, getting frustrated, please help if you can.Thanks, Dave Fisher.
