Do you mean the stock electric fan in front?

My electric fan threw the tiny belt that turns the passenger side of the two fans.
The one on the right has the motor. The one on the left has a tiny belt.
Looks like that part is available.
I think I will just remove the fan.

Grrr.. This seems like a knuckle shredder.

In case you are still wondering, there is a hole on the back of the water pump flange that can be aligned with the Ridge on the top of the water pump.
Align the hole just to the driver side of that Ridge and place the tool (there is actually a tool made for this; I used another tool and also think one could be made. Once you have it aligned you will see how it works and what will work to hold it in place.)
When you turn the bolt the tool that you use will act as a stop on that ridge.
When you put it back together just align the hole on the passenger side and it locks it as you tighten the bolt.
If I was home I would get pictures of it for you but I just did this job about 4 times on my 99 (don't ask!).
As previously posted, unbolt the 4 tens holding the upper rad support as this allows just enough room b/t the rad and clutch fan bolt

Thanks hogweed.
I'm gonna try to hold the belt the stupid first and then I will take a look at your suggestion.
BUt I will loosen the rad support.

Cutting the allen wrench was the hardest part.

I didnt even have to pull the rad support. But it looks like I have to pull it to replace the belt on my electric fan... its missing.

I didn't block off the belt. Just used a 2 foot cheater bar and braced my right hand against the power steering pulley and gave it a medium yank to break it loose.

pizza box helps here. cut it open and slide it in.

Okay Ive seen this suggested in various situation and Ive tried to cut an allen wrench which is tool steel, like cutting...tool steel. Tempered, hardened and no saw will touch it, so how, really, do you cut an allen wrench? grinder perhaps? Space alien tech or dental drills? Lasers? Plasma torch?

Dremel with a cutoff wheel. Wear eye protection, use a vice.

I used a masonry cutting wheel on a beat up old ryobi saw.

But a grinding wheel from grampas work shop would work.

If you don't have either of these get a grinding wheel for your power drill from a hardware store.

If you can't do that you could put it in a drill as a bit and spin it against an old school metal file and

If you cant do that rub it against a rock for a few hours.
