I do not have my truck here to compare...but something looks odd on the front of that engine (to me).
Mine has a pulley on the water pump and a spacer for the fan which puts it out about half way in the shroud.
My only belt goes around the crank, water pump pulley, and the generator.
Maybe I am wrong.........
I will look closer tomorrow when I get up. I won't get home until around 1 AM. LOL
