INA Drive Belt Idler Pulley (Grooved) Right Upper, part number 5320866100, from INA — a German engineering brand renowned for OE and aftermarket automotive components. This grooved drive belt idler guides and tensions the serpentine belt, helping maintain proper belt alignment and reducing wear on other pulleys. Built to INA's precise standards, it delivers reliable operation and long service life in demanding engine bays.

Ideal for select Mercedes-Benz applications, this idler helps restore smooth belt operation after bearing wear, contamination, or misalignment can cause belt squeal, slippage, or tension loss. Replacing with the INA pulley supports proper belt tracking, engine accessories performance, and quieter, more reliable starting and operation.
