Did it on a 2005 Fleetwood Excursion with a C7. It took two people, one on top in the closet and one from underneath to get the belt around the fan blades and around all of the pulleys correctly.
Take a white or silver marker and draw a diagram of where the belt goes around everything on the black fan shroud where it's easy to refer to from underneath.
You might look at changing your antifreeze overflow tank if it's still original. The plastics they used on them were real **** and almost of them start leaking from heat stress cracks. This will save you from taking everything out of the closet a second time and problems out on the road.
