You should have a 3 groove crank pulley, 2 groove power steering pully. So, the first belt on is the ac, the pulley clostest to the engine block : crank-power steering-AC. Then crank - power steering, or crank-water pump-power steering. Then crank - water pump- alternator. The power steering belt routing is preference. It can go on the water pump but it doesnt have to.
