Your local parts store should have a belt routing diagram in their serpentine belt catalog. I know for a fact that NAPA and Carquest can provide you with this.
The online AutoZone diagram was wrong. Take a photo of it.
Make sure the new belt is the same size.
Got a 2001 Crown Vic, Police Interceptor, was replacing the serpentine belt, got called away after taking it off, forgot how it went back.
To no avail the internet was useless, wrong pic; but others had the same question. Remembered I had taken a lot of photos when I replaced intake, and there was the magic photo that saved my day. others!
Put up a photo on my site:

There should be a sticker on the fan shroud or on the bottom side of the hood. If your sticker is missing, that is the same truck I drive. I could post the routing sticker somehow.
There should be a sticker under the hood with the proper routing. If it is missing, your local dealer should be able to print out a copy of the routing.
Check under the hood for a black and white sticker. Should be labelled serpentine belt routing.
look at the drivers side of the radiator the should be a white sticker that has a picture of the routing
When routing a new serpentine belt, make note of how the old belt was routed. Take a picture of the belt routing if possible. Also most cars have a sticker under the hood with the routing on it.
THERE IS A STICKER ON THE LEFT SIDE ON TOP OF THE PULLEY'S IT SHOWS YOU HOW TO THREAD IT.
Check the manufacturer's routing sticker under the hood.
You should have a belt routing diagram sticker on top of the radiator shroud. I've also included a video that shows right where this sticker is and how to replace the serpentine belt on your truck.
Open the hood and there will be a sticker by the radiator (right above the grill) showing belt routing.
There should be a sticker under the hood right around the lever to open it, the sticker shows you the correct way.
Either in the owners manuel or on a sticker under the hood of the car.
In the engine compartment, somewhere in front of the top of the radiator, there should be a diagram sticker showing how to run the serpentine belt
