dieseldo, there is a special wrench set you can buy to get the fan & clutch removed that makes it much easier. I ended up buying them ($40-50 IIRC) since I knew I'd be doing it again in the future. If you have a wrench that fits, you'll be fine. The 2nd wrench fits over the pully bolts to hold the pully which is not necessary, it just makes it a bit easier.
Oh, and I'm not exactly the brightest light on the tree, so when I read the sticker on the fan shroud that says the fan clutch is "right hand thread" I assumed it was not normal. I didn't bother to think about it. If I had I would have saved a bit of time! righty tighty, lefty loosey.
It's a fairly straightforward job.
