Alternator replacement DIY? '01 3.0L

[DillonInCO]

Well, my X5 left me stranded for the first time the other day. The battery light came on solid red while I was driving around. I got maybe a few miles after that and had to be towed home. I'm wanting to replace the alternator myself to save money---they are ridiculously expensive enough already---but one look at its location has me going, uhhh...where do I start? Searched for some DIY write ups but all I found was for the V8s. Maybe it's the same as the 3.0L E46 or E39 (lots of write ups on those)? Or maybe I wasn't looking in the right spot? Thanks in advance.
