Powertrain / Under The Hood • How many coolant hoses and part numbers?

my upper radiator hose shows signs its been leaking. I would rather replace them all because I dont know the age and would rather pay for the coolant one time.

I believe I found the Motorcraft hoses for 8260 and 8286a

Upper hose listed as 8260 in the diagram - Part#:KM5017 (AA5Z8260A)

Lower hose listed as 8286A in the diagram - Part#:KM5018 (AA5Z8286C)

Does anyone know the part numbers for the 8286B or 8C289 in the attached diagram?
