You can borrow the kit at Autozone, no need to buy it.

You have to hold the pulley in place while you turn the nut that holds the fan clutch, and fan, on. This nut is a reverse thread, to the rule of Lefty Loosey Righty Tighty is reverse. Turn this nut to the right to loosen it.

Fan nut is 32mm

It is a 32mm nut, but you can also substitute a 1 and 1/4" if you can't find a 32mm where you live. Personally I just put the wrench on the nut and give it a good whack with a mallet to avoid having to use special tools. That technique has worked for me lots of times, but use it at your own risk and be careful not to smack the side of your expansion tank with the mallet. REVERSE threads btw.
