As far as I know, you only have to remove the pulley, and the pump. It's not too bad, to do the same on my car you have to remove several oilpan bolts, most of the front dress, the water pump, fan and clutch, oil pump and the chain casing. Then unbolt the seal and put everything back on.
Shouldn't be too hard to do, there's an HMA service somewhere on here to show you how to do it. I don't know the link, but it's on here somewhere. .
