The functioning of a tensioner belt pulley is relatively straightforward yet essential for a reliable engine operation. The tensioner itself is a spring-loaded device that applies pressure on the pulley to keep the belt tight. The spring mechanism compensates for any slack in the belt that may develop due to wear or changes in temperature. As the belt stretches over time, the tensioner pulley adjusts its position to maintain optimal tension.
