Q: What are the drive belts and why are they important for engine and accessory operation?
A: Drive belts, or V-belts, at the engine front, are vital for engine and accessory function. Check belts for cracks, separation, fraying, and glazing, and pulleys for nicks, cracks, distortion, and corrosion. Belt tension can be checked by pushing it halfway between the pulleys. If needed, adjust by moving the belt-driven accessory. On newer models, a tensioner automatically maintains belt tension. To replace a belt, follow adjustment procedures and ensure correct routing.
