Solution: Replace the belt and make sure to realign the pulleys. Also check that the pulleys, pulley brackets and shafts are not bent or broken.

What damage can a broken serpentine belt cause?

This can lead to a sudden lost of power assist for the steering system, leading to the steering wheel all-of-a-sudden becoming very hard to turn. A broken serpentine belt may stop the water pump from circulating coolant through the cooling system, causing the engine can overheat.
