Dayco 89014 No Slack Idler Tensioner Pulley is a 109 mm diameter, 6-groove belt pulley with a flange, designed to function as the no-slack idler in serpentine belt tensioner assemblies. It maintains belt tension and guides the belt along the drive path to prevent slippage and misalignment in the belt system. The flange helps keep the belt aligned within the pulley groove for consistent operation.
