there is an idler or tension pulley above the alternator but closer to the water pump pulley, feel just below the top belt and you will feel a casting for a 17mm socket head. I had to use a cheater bar on the end of my is something very helpful if you look at the tension housing you will see two castings that appear as though a small bolt would fit through if they were lined up and that is correct this allows you to release tension on your ratchet and change out the belt.
