I have changed the alternator a few times on mine and on others (once in the rain)... but have done it with less work
I remove the water outlet on the head, remove the alternator bracket, undo the rad mounts (top) to get some wiggle room, upper rad hose (obviously), and then spin the alternator so the pulley faces up and pull/wiggle it out, it's close
This is with a slightly thicker NX radiator, a/c, and I have a BBdet... no need to remove the passenger mount in my experience
If you need an inch extra space you can jack the engine up SLIGHTLY without mount removal but I have never needed to but each situation is different.
Hope this helps some.
