How to Select a Fan Belt

Fan belts are typically found on older cars, and connect the radiator fan to the alternator and the drive shaft. Manufacturers now use drive belts, accessory belts or serpentine belts, which refer to the continuous loop belt that powers several engine components, such as the alternator, power steering pump, water pump and air conditioner compressor. Choosing the best belt for your vehicle prevents problems and keeps your engine running smoothly.

• 5

  Choose from one of the available belts specified to fit your vehicle. The best belts come with a warranty; do not buy one without it. Also, ribbed belts perform better than smooth belts. These ribs, placed at regular intervals along the belt, help the belt grip, and lessens the chance of malfunction. A W-shaped rib offers a better grip than the standard, V-shaped rib. Also, buy only reinforced belts, which increase durability.
