On the car listed above the engine had a cover which showed the routing of serpentine belt. Someone removed and stole the cover. You show several serpentine belt routings for this car. I have the VIN for this vehicle. Can that be used to determine which of the routing diagrams is the one to use, or is there another way?

There's three versions of the 3.0L engine. This first drawing is for "Vin S". The second is for "Vin U", and the third is for the flex fuel version. It looks like the last two are identical, but I posted them separately just in case there's some difference I didn't see.

When you're done installing the belt, to double-check, the ribbed pulleys must have the ribbed side of the belt driving them, and the smooth backside of the belt must be running on the smooth pulleys.
