You can get by without removing the radiator or ac condenser; all you need to do is remove the passenger cooling fan and disconnect the upper radiator hose and move it out of your way. (Coolant will leak if you don't drain out about half a gallon) That will get you access to the front bolt by the exhaust manifold (doesn't completely remove just loosen it and leave it in the hole). From the under side you can get to the rear bolt. I have seen a lot of people's responses to this saying you have to take of tons of stuff that is not necessary; so here is the list:
Remove passenger tire, inner fender and splashguard (gives access to the lower bolts on the alternator)
Goes without saying but… disconnect your battery and remove it.
Under the car, remove the plastic dust cover running between the frame rails (three 10mm bolts)
Directly under the alternator there is a small access cover (metal) with 4 bolts; remove it.
Take the serpentine loose from the tensioner and slip it off the alternator.
Remove the passenger side motor mount from the core support.
Remove the ground from the bracket the motor mount attaches to.
Remove the bracket that the motor mount attaches to.
Remove the remaining bolts from the alternator on the passenger side.
Remove the remaining bolts form the alternator on the driver's side (from under the car)
Slip the alternator down through the small access cover you removed earlier. Having the pulley orientated toward the driver's side works easiest so just rotate it till the pulley is facing the drivers tire. (It is still a tight squeeze but it will come down; be careful not to dent up the radiator.)
After you complete those steps just reverse them and you should be done in about an hour and forty-five min. The first time it took me two and a half hours to complete the entire job. Hope this helps because there aren't many good how-to's on this make and model.

I have a '98 STS with the Northstar and was recently on Cadillacforums.com and the same question was asked about the northstar and alternator. From what I remember, You have to take the right radiator fan out, take passenger side tire off, I think remove the black plastic (might be in the way) and you should be able to get at it from there. word of caution though, watch you dont bash the radiator in when you turn it to get it out.
disconnect battery. remove electrical connections from alternator. remove serpentine belt. remove alternator mounting bolts and remove alternator. Installation is reverse of removal.
