Here you go!

Remove or disconnect the following:

Autozone does not give explicit instructions on the replacement. They simply state the obvious however, I imagine that would suffice the novice.
There are two approaches to the removal of the alt on an 01- Mit Montero spt.
1. Discont Neg Bat Cbl then air box and fan shroud along with the fan, (the top radiator hose may need to be removed for some to remove shroud), Loosen all belt tensioners and remove belts. Remove bottom skid plate and remove alt not forgetting to disconnect its wiring. It is important to ensure all connections, cables, brackets, and "paths" are clean and corrosion free.
2. Disconnect Neg bat cable, remove bottom skid plate, remove pass frnt tire for access, loosen tensioner of alt belt and remove belt, loosen alt bolts and remove making sure to unplug any wires or connections on back of it. This is a little less time consuming and a tad more puzzling as you have to "maneuver" the alt around hard lines and hoses out thru the bottom. Make certain you stay away from damaging the radiator during any of these methods.
That's my two cents and with that, I will go time myself on an alt swap. I'll let you know. lol!
