There are so many possible ways to route a serpentine belt on a vehicle. Which one used depends entirely on the engine, the accessories installed, WHERE they are installed, what pulleys were installed on the accessories, etc.
Search around the engine access panels/doors/hood for a manufacturers sticker showing the belt orientation. You might get lucky (don't hold your breath though).
PICTURES.....of the overall face of the engine where the pulleys are and detailed enough pictures to identify which side of the belt each pulley bears upon are the minimum needed without a specific belt installation drawing. Even then, there could be multiple paths depending upon the length of the belt.
We've done so much, for so long, with so little, that we can now do the impossible, overnight, with nothing.
