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.
There is a plate under the car on passenger side. Remove this plate and you will be able to see the alternator. I think it has three bolts.
