How do you change a v belt and the other belt on a 1985 fiero gt?

To change the V-belt and the other belt on a 1985 Fiero GT, first, disconnect the negative battery terminal for safety. Loosen the tensioner by turning the adjustment bolt, then remove the old belts from their pulleys. Install the new belts by routing them according to the belt diagram usually found on a sticker in the engine bay, ensuring they sit properly in the grooves. Finally, adjust the tension on the belts, ensuring they are tight but not overly so, and reconnect the battery.
