What is a fan belt?

A fan belt, also known as a v-belt or a serpentine belt, is a rubber belt that connects various engine components to the crankshaft in a vehicle. It drives components such as the alternator, water pump, power steering pump, and air conditioning compressor, among others.

The fan belt is responsible for transferring power from the engine to these components, allowing them to function properly. It is typically made of rubber reinforced with cords or fibers to provide strength and durability. Over time, the fan belt may wear out, become cracked, or stretch, which can lead to mechanical issues such as loss of power steering, overheating, or battery not charging.

Regular inspection and maintenance of the fan belt is important to ensure the smooth operation of the vehicle and prevent costly repairs. It is recommended to check the fan belt for signs of wear and tear, such as cracks, fraying, or glazing, and replace it if necessary. It is also advisable to follow the manufacturer's guidelines for maintenance and replacement intervals.
