Difficulty, time, and cost are estimates when this guide gives them. Torque is a cited figure, or it is left off.

The normal schedule lists inspect accessory drive belt or belts at every 100,000 mi (160,000 km). Footnote 3 says after the initial inspection, inspect every other oil change until replaced.
Replace accessory drive belt or belts is in the every 150,000 mi (240,000 km) block, with the automatic-transmission fluid and filter and the axle and transfer-case fluid lines.
The capacities pages show a drivebelt routing figure. The path is not written as a pulley sequence, so this page does not draw one.
The normal scheduled maintenance table in the third-printing 2018 F-150 manual puts inspect accessory drive belt(s) on the every 100,000 mi (160,000 km) line, next to replace spark plugs. Footnote 3 on that inspect line says after the initial inspection, inspect every other oil change until replaced.
Replace accessory drive belt(s) sits in the every 150,000 mi (240,000 km) group. The same group lists the automatic transmission fluid and filter, front axle fluid on four-wheel drive, rear axle fluid, and transfer case fluid on four-wheel drive. Footnote 1 says to perform the items within 3,000 mi (4,800 km) of the last engine oil and filter change, and not to exceed the designated distance.
Routing drawings are on the capacities pages. They are figures, so no pulley order is copied here.

Same repair, different model year. Use the page that matches the truck or car in the driveway. A figure on one year is not a figure for the next.
