1989 IROC-Z 5.7 TPI. How do i check if the engine has completely seized up? I have heard about turning the crank with a breaker bar. If i was to do that, what equipment would i need? What size is the nut on the crank wheel? Is there any other way to find out if the engine has completely seized up? as of now the starter will not move the motor at all. I can tell this by watching the alternator while i turn the key. Any info is greatly appreciated.
