First, you disconnect the battery negative.
Put a socket and ratchet or breaker bar to the belt tensioner, twist counterclockwise to loosen the slack on the serpentine belt. While you have slack on the belt, pull it off the alternator pulley. There'll be a quick connect with some electrical lines going to the alternator. Disconnect that. On the back side of the alternator, there'll be a stud with a nut on it, and connected to that stud will be a wire with a ring terminal (this wire will run from the alternator to the battery positive). Disconnect that wire. Not being familiar with this specific model, I don't know exactly where the bolts are or how many there are, but you'll see them if you look around the alternator.. should be two or three bolts. Remove those, and the alternator should come out.

How do you replace the alternator on a 2001 BMW X5 V8?
this is just like any other alternator on any other car. first disconnect battery, next remove the serpentine belt but make note of its routing so you will know how to install correctly. next the alternator is located on the left bottom on the engine. sudjest removing from the bottom, remove connector and main chargine wire from rear of alternator, unbolt bolts and remove alternator, if this seems to complex then take it to a BMW dealer to have it performed, also i recommend a approved BMW alternator, prefer actual BMW one.
