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