Detailed Product Description

The Dorman 419-626 idler pulley is a critical component in the accessory drive belt system of Nissan Altima vehicles. Its steel construction provides the necessary rigidity to withstand constant tension and rotational forces. The pulley features four grooves designed to guide serpentine belts accurately, preventing slippage and premature wear. With an outside diameter of 86 mm and a 10 mm inside diameter, it fits precisely within the belt routing system. The single mounting hole ensures a secure attachment point, while the integrated bearing with a 12 mm width supports smooth rotation and reduces friction.
