Fan clutch fix/replacement

Lately, my engine started to overheat (to the point that the radiator exploded, but that's another story).
I have repaired the radiator (and checked for clogged channels, etc), changed the thermostat, but seems that the problem is the fan.
So, I decided to replace the fan clutch, but without too much success.
Here, in Romania, is hard to find a suitable fan wrench, so I have tried with a big adjustable wrench (it is the infamous 2000 clutch, that's fixed by the means of a big nut). No chance. I have tried to block the pulley with a screwdriver (used as a lever, against two of the bolts on the pulley), but all I did was to bend the screwdriver, without the nut getting loose.
I will try tomorrow, once again, if not, I will go to the stealership.
Meanwhile, I would like to know if anyone ever tried this: Pirate4x4.Com - Fan Clutch Trail Repair
The soonest I can have a fan clutch is within two weeks and I desperatly need the Jeep meanwhile. So, supposing I willl manage to get the fan clutch out, would the fix, presented before, work in the case of Jeep clutches as well?
Thanks

Never seen that one, it would help if they had a couple more pics to get a better idea of it. I would see if anyoen on pirate actually has more info on that trail repair cause it sounds interesting.

Here's a write-up for typical replacement

I followed the steps, but couldn't manage to unscrew the fan clutch (I didn't use the fan wrench, 'cause I don't have one, I have tried with a large adjustable spanner).

That nut is a pain in the a**.

Could someone specify the exact tool recommended for removal? Is it a universal fan clutch wrench? Or do they make a specific spanner wrench that matches up with the holes on the water pump?

Thanks

Another option is to use a ratchet w/NO socket and put into the hole/slot at the idler pulley or tensioner I believe and using either piep wrnech or cresent wrench instead.

The ratchet against the pully/belt should help with tension so you can break the fan nut loose. It does help to have another person there helping. I believe that the fan clutch is opposite threaded as well... I think left hand thread... check in the link I posted.
