disconnect negative cable, flip the belt off, remove plug and positive wire from alt. loosen the bottom nut (14mm), remove the top bolt and the 2 bolts that hold iron bracket ot front of engine.
Rock the alt back-forth while lifting it up out of the hanger. Remove alternator..
If using the Hyundai re-man alt, you will need a shorter belt as pulley be smaller to spool up alt at slower speeds (alt been changed too).. thee '111 belt may be too long, replacement to use with new alt is '181
