Are you sure they used that method back in 1990? My '93 four cylinder still has the style that has four bolts that go through the fan and pulley and bolts to the water pump.The clutch (with fan) simply unscrews, the opposite direction of the fan's rotation. You can rent wrenches for this from auto parts stores (I just use a mallet and brass rod and tap the clutch loose).
Once off, the fan unbolts (4) from the clutch.
Pretty sure, without pulling a manual or going out and looking (although, I am getting to where I can't remember if my memory still works).Are you sure they used that method back in 1990?

Dog-gone autospell/autocorrect AI bs!!And how does Dan feel about that?
Ha ha! Autospill and autoconnect will be the death of all of us human servants.Dog-gone autospell/autocorrect AI bs!!
What do you mean smooth?2.9l should use the screw on kind of fan clutch in 1990
It uses standard threads so "lefty loosy-righty tighty"
But easy way to tell if its standard thread or reverse thread is to look at the water pump pulley
If its smooth then regular threads
If it has ribs then Reverse threads(like 3.0l)
But the fan clutch nut is hard to break loose regardless of thread direction, lol, because you need to hold the water pump shaft tight to loosen the fan clutch nut
There is a Ford tool set for that: https://www.amazon.ca/Powerbuilt-647074-Ford-Clutch-Wrench/dp/B004KEJXGE?th=1
Not recommending this set, but it has images on how it works
The wider wrench goes around the 4 water pump pulley bolts to hold it from turning
You can use a strap wrench on water pump pulley to hold it
Or if you loosen one of the 4 bolts on the pulley you can use a screw driver behind the bolt as a lever to hold pulley
Once you break it loose it easily unscrews
