BMW OEM Idler Pulley for G8X M2/M3/M4 (11287589361)

The drive belt idler pulley works with the tensioner pulley and tensioner assembly to maintain belt tension and guide the belt around engine accessories like the power steering pump, water pump, A/C compressor, and alternator. Although often overlooked, the idler pulley is crucial for proper belt routing and function. It is generally recommended to replace the idler pulley along with the belt tensioner. Symptoms of idler pulley failure include visible wear or grooves, belt squealing, chirping or grinding sounds from the pulley bearing, uneven belt wear, and misalignment with the mounting surface.
