How remove a crankshaft pulley of a geo prizm 1990?

To remove the crankshaft pulley from a 1990 Geo Prizm, first, disconnect the negative battery terminal and remove any accessories attached to the pulley, such as the serpentine belt. Use a socket wrench to remove the bolt securing the pulley; you may need to use a breaker bar for additional leverage. If the pulley is stuck, gently tap it with a rubber mallet or use a puller tool to help detach it from the crankshaft. Always ensure the engine is cool and take safety precautions throughout the process.
