Q: What are drive belts and their importance in a Pontiac Firebird?
A: First of all, drive belts should be regularly inspected. Newer models use a single serpentine belt with a spring-loaded tensioner pulley, requiring no adjustment. Inspect belts for cracks, separation, fraying, and glazing, and check the tension by pushing halfway between the pulleys. If adjustment is needed, loosen the accessory's adjustment and pivot bolts and move accordingly.
