To tighten the alternator belt on a 1989 Nissan Pulsar, first, locate the alternator and identify the tension adjustment mechanism, which typically consists of a bolt and a pivot point. Loosen the mounting bolts on the alternator, then use a wrench to turn the tension adjustment bolt to increase tension on the belt. Ensure the belt has about half an inch of deflection when pressed in the middle, then tighten the mounting bolts securely. Finally, check the belt's alignment and ensure it's running smoothly on the pulleys.
