I just replaced the compressor and drier on my 2001 3.0 duratec not long ago. Was proud of myself for being able to do it. A lot to take apart but if you take your time you can do it. I used up most of a 3 day holiday weekend to do it.
I was als able to get a used copy of the service manual (2 volumes!) from Faxonautolit.com. They seem to have a lot of manuals there. Also picked up the one for my 99 Durango. I looked at them and them proceeded to throw away my Haynes and Chilton Manuals. Their useless in comparison. These are the real deal.
Good luck
