So what exactly is a key way?

the gear is behind the pully right?

a key way is a little notch in the crankshaft where the pulley sits, it keeps the crank pulley in an exact place so the timing marks line up so you can time your car correctly.

yeah, my mechanic friend told me to do the same.
I guess the sudden force will break the threads loose.

once the bolt is loose, does the pully just spin around?
or does this keyway stop it from moving? [/b]

Yeah the sudden force will break the bolt loose, the bolt from the factory has like 230-260ftlbs of torque on it, plus its been sitting in there for awile, so its gonna take some time and patience to get it off. Like i said, dead blow and ratchet, and alot of penetrating oil.

try using an impact first, then maybe the dead blow.
