How do you change an alternator fan belt on a Mazda 323?

To change the alternator fan belt on a Mazda 323, first, ensure the engine is off and cool. Locate the alternator, then loosen the bolts securing it in place to create slack in the belt. Remove the old belt and install the new one by routing it around the pulleys, ensuring it's properly aligned. Finally, tighten the alternator bolts to secure the belt, making sure it has the correct tension before closing everything up.
