94 Pontiac Grand Am replacing power steering belt

I have a 94 Grand Am and need to replace the steering belt. It is a 4 cylinder with the over head cam. The power steering belt is located on the driver's side. How do I loosen the tensioner? Is it on the top pulley or the bottom pulley and what do I need to loosen it with?

Welcome. Loosen the pump, it will pivot on one bolt and the other holds it in place. Make sure you loosen both bolts, and don't forget to tighten both as well.
