Quizplus · Accepted Answer

Timing belts and serpentine belts are designed differently; timing belts have teeth to mesh with the gears of the engine's timing system, while serpentine belts are smooth and drive accessories like the alternator and water pump. Technician B is correct because a timing belt that is adjusted too tight can indeed whine due to the excessive tension.
