Like any other component of a vehicle, the fan belt is subject to wear and tear. Over time, exposure to heat, friction, and environmental factors can cause the belt to crack, fray, or stretch. Neglecting to monitor the condition of the fan belt can lead to severe engine problems. A failed fan belt can result in overheating due to the water pump not functioning, a dead battery because the alternator is not charging, or even a loss of power steering. Therefore, regular inspections and timely replacements of the fan belt are crucial to avoid costly repairs in the long run.
