DESCRIPTION
The idler pulley with part number 4987970 is a small, but important component of a truck's engine. It is responsible for maintaining tension on the serpentine belt that drives many of the engine's accessories, such as the alternator and power steering pump. The idler pulley is typically mounted to a bracket on the engine block or cylinder head and spins freely on bearings. Over time, these bearings can wear out causing unwanted noise or even failure of the pulley itself. Regular inspection and replacement of worn idler pulleys can help ensure reliable operation of a truck's accessory drive system.
