I didn't have to remove my lower radiator hose, but was able to just barely squeeze it out with the alternator facing downward. Picture attached for reference if anyone else is trying to remove it from the bottom. Stock alternator lasted me 182K miles.Too much effort. Take off the air cleaner. Remove the serp belt. Unbolt the PS pump, move it aside. Undo the alt bolts, take off the alt downward, remove from below. I found it easier to do with the radiator hose off, some folks have done it with hose in place. Don't remove radiator overflow, don't remove PS reservoir, don't undo PS hoses.
