The entire A/C refrigerant system can be removed (or INSTALLED) as a unit from all '80-96 gasoline (& probably diesel) F-series & Broncos without much trouble. The fan & shroud have to come out so the radiator can tilt back, and the belt has to come off, of course. But no coolant, refrigerant, or other fluid lines have to be opened.

If you're just cleaning the evaporator core, nothing else needs to be removed.
