Signs of a Failing Serpentine Belt:

  • High-Pitched Whining Sound: The belt slipping on the pulleys can cause a distinct, high-pitched whining noise that increases with engine speed.
  • Inability to Steer: If the power steering pump isn’t receiving power from the belt, you’ll experience very stiff steering, making it difficult to turn the wheel.
  • Loss of Electric Power: An alternator failure caused by a faulty belt can lead to a loss of electric power, resulting in dimming lights, a non-functional radio, and eventually a dead battery.
  • Reduced Air Conditioning Performance: A failing serpentine belt can weaken the air conditioning compressor, leading to decreased cooling performance.
  • Engine Overheating: The water pump, if powered by the serpentine belt, can fail to circulate coolant properly, leading to engine overheating.

Staying Ahead of the Curve: Preventive Maintenance Tips

While a failing serpentine belt is a common car problem, it’s easily preventable.

  • Regular Inspections: A quick visual inspection of the belt during routine maintenance can help identify potential cracks, fraying, or excessive wear.
  • Recommended Replacement: Most manufacturers recommend replacing the serpentine belt every 60,000 miles or every five years, whichever comes first.
  • Proper Tension: An overly loose or excessively tight serpentine belt can also lead to premature wear. Ensure the belt tension is within the manufacturer’s specifications.
