Alternator Idler Pulley
The alternator idler pulley is an important component in a vehicle’s alternator belt system. Its main function is to adjust belt tension and prevent vibration or slipping.
This component is designed as a pulley or roller mounted on a bearing. As it rotates, it ensures that the alternator belt moves along its correct path, guaranteeing optimal performance of the alternator and other belt-driven components such as the power steering pump and air conditioning compressor.
