The automotive tensioner pulley (also known as a belt tensioner pulley or idler pulley) is a critical component within the vehicle's drive train system, designed to maintain appropriate tension on belts or chains. Typically positioned near engine components such as the timing belt, alternator belt, or air conditioning belt, it applies pressure to the belt via a spring or hydraulic mechanism. This prevents slackening or slippage during operation, ensuring synchronised functioning of all connected components.
