If you run a search you should find a few threads on this subject.
The method I used, and seems to work for other people to, is to unbolt the clamps at the top and unbolt the shroud.
Once thats done pull back the shroud, its best to remove the mechanical fan when doing this, and pull out the radiator before you pull out the shroud. Get someone to help you, makes life easier. I always lifted the drivers side first because the spout on the passenger side would get caught on the A-arms.
The shroud comes right out.
do in reverse order to assemble.
