Serpentine BeltThe serpentine belt was first introduced in 1985 by Mercedes. The serpentine belt was designed to replace the multi belt drive belt systems and control multiple components on your engine with a single belt. The single belt is more efficient, easy to change and has a longer life span than the multiple belt systems used in earlier model vehicles.
The use of a serpentine belt requires a belt tensioner or idler pulley to apply the necessary tension to the belt. The use of a tensioner pulley or idler pulley also makes changing your belt a lot faster and easier than multi belt systems.
