For most cars there is a separate pulley groove and belt for the alternator and Power Steering.
That way if your alternator belt breaks you could still steer the vehicle.
2 belts, 1 from the alternator to the water pump pulley and down around the crank pulley and the other belt goes around the water pump and around the crank pulley to the power steering pulley if you have power steering.
Power steering usually powered by that pulley.
It's on the passenger side of the engine, beneath the power steering pump. If you look at the crank shaft pulley, the alternator belt is the innermost belt.

the belt only goes around the crank pulley and alternator pulley
Seized should mean that it's not turning. Crank the engine and see if the alternator pulley spins or not.
the pulley on the harmonic balance drives the alternator belt. this is the pulley at the bottom of the engine ,on the front of the crank shaft if this pulley is not turning you have a problem. this means either the key is missing or the crankshaft is broken
Starting from the crankshaft pulley and going clockwise looking at the pulleys, the belt goes thus: Ribbed side against the crankshaft pulley, then flat side against the tensioner pulley, ribbed side around the power steering pulley. Then the flat side against the idler pulley running ribbed side around the alternator pulley then down to theair con pulley running ribbed side around that and back to the crankshaft pulley.
Crank pulley Piston connects to the crank shaft. One side of the crank shaft connects to the transmission and the other side connects to the crank pulley. It serves two main purpose. First one is it is used to time the engine (marks etched into it by manufacture) the other is to power other devices such as the alternator or power steering via a belt system (older cars used chain and gear sys). It is usually found closes to the bottom of the engine at the front, just follow the belts to the bottom.
The water pump pulley is the pulley right above the crank pulley (the big pulley in the bottom of the engine.) Right above the water pump pulley should be the alternator pulley, which drives the alternator. I'm guessing the water pump is behind the WP pulley. == == == ==
which one the power steering,alternator,crank or a/c,crank?
I'm not real sure i understand the question.the question alludes to a "drive" (as in transaxle) mechanism requiring a "drive" belt. Referring to serpentine "drive" (pulley) belts for alternator, power steering and water pump:most cases require you to loosen the alternator adjusting (tightening) bolt and/or the power steering pump adjusting bolts. I had to replace a broken alternator belt a few weeks ago in 15* weather (outside). I had to use a "push" tool to force the beltbetween the pulley on the alt. And the other pulleys to get over the crank pulley.
