The idler pulley maintains proper belt routing and tension for the water pump and other accessories. When the pulley bearing wears, it can cause belt squeal, wobble, or slipping, leading to overheating or accessory failure. This Haldex Like-Nu unit is a cost-effective replacement for the original Cummins pulley.
