Re: 98 f150 a/c compressor removal
Dont know if this helps or applies to your vehicle from another site ,
" I have a '97, 4.6 myself, and I went and did the compressor replacement.You do have to remove the fan shroud and get remove the fan (it makes it A LOT easier). Removing the shroud and fan itself makes it a whole lot easier to get to the tensioner...which you'll need to get at with a 1/2" wrench to loosen the serpentine belt off.
The only complication I had was holding the fan to remove the large nut which it holds itself on. But I fabricated a tool out of some flat stock which bolted to the fan clutch's 5 (or 6, i cant remember) bolts, which made it more simple to remove.
You could however, get an extra set up strong hands to hold the fan with some leather gloves. That might work just as well. "
