At the risk of losing my credibility, there is one last resort solution before using the torch. You can drill a 5/16 inch or so, size hole in the fan pulley then stick a metal pry bar or similar in the hole the keep the pulley from turning. Its crude, but effective. You will likely have to file down the distortion that will occur around the hole from the pry lever.

I guess I should have said that I had removed the waterpump/fan clutch assembly after all of my attempts at removal failed. Even with the thing in a vise, we couldn't turn it, and this was at the dealership, with all of their "experts" giving it a shot...lol

My '93 3.0L has left hand thread, and my '95 4.0L has right hand thread. It should say so clearly on top of the fan shroud.
What to do if the shroud is not original?

Don't hold me to this for I might be very wrong, but I think you may be able to tell by the way the waterpump turns while the engine is running. When the pulley turns clockwise (looking at it from front to rear), you have left hand thread so the friction from the fan clutch would tend to tighten it into the water pump. If the pulley turns counter-clockwise, you have right hand thread for the same reason. At least that's the difference I see between my 93 3.0L and 95 4.0L.

It seems to me, we tried to loosen it in wrong direction with so enthusiasm and fanatism, that it is titen so well with so extremal torq. that I don't know how to loosen it! When I tried to rotate it by wrench, crankshaft turns too! I tried to put the screw driver to bellhousing to prevent it, and pulley skids! What to do?

However, Pablo's van doesn't even have the original engine or fan shroud. I think he said they cannibalized a couple of engines to make what he has in there now. In a hospital setting, it's like doing a vasectomy on a patient that might or might not be a male 
Hi Pablo:
Wrap the belt around the pulley and put a BIG pipe wrench on the belt. You might have to double up the belt to make sure you don't damage the pulley. But then you would probably ruin the belt. What has always worked for me is to leave the belt on the pulley as is, put a heavy wrench on the fan clutch nut, then strike it hard with a hammer. That's about as close to an impact wrench as you can get

Anyway, did you try removing the fan blades first to get some room for a BIG pipe wrench? Other than the pipe wrench, I see no other way if it's that stubborn. The nuclear option would involve making a heavy steel plate to fit on 2 of the 4 bolts on the pulley and weld a big breaker bar in there to keep it from turning. But I never tried that before since I have no welding equipment. If it really comes to that, I think it'll be easier and cheaper to just remove the waterpump along with it and put in a new waterpump and a new fan clutch.
