How do you install an alternator belt on a 93 Ford Festiva?

To install an alternator belt on a 1993 Ford Festiva, first, make sure the engine is off and cool. Loosen the alternator mounting bolts to create slack in the old belt, then remove it. Position the new belt around the alternator and other pulleys according to the belt routing diagram, ensuring it sits properly in the grooves. Finally, adjust the tension by repositioning the alternator and tightening the mounting bolts, ensuring the belt has the correct tension before closing the hood.
