metric variable speed belts

A tensioner belt pulley is typically constructed from durable materials such as metal or high-grade plastic, designed to withstand the high temperatures and stresses present in an engine environment. The pulley is mounted on a pivot arm, allowing it to move as the belt tension changes. Most modern tensioners are equipped with a spring mechanism that automatically adjusts the tension on the belt, providing a consistent and precise amount of tension regardless of engine speed or load.

A timing belt is a rubber band with high-tensile strength and is anchored with fibers and teeth. It synchronizes the rotation of the engine’s crankshaft and camshaft(s), ensuring that the engine's valves open and close at the correct times during each cylinder’s intake and exhaust strokes. Without a properly functioning timing belt, your Nissan's engine performance could significantly decline, potentially leading to catastrophic engine failure.
