Description
000 202 07 19 – Mercedes-Benz Drive Belt Idler Pulley (Grooved)
This pulley is a vital component of the engine’s accessory drive (serpentine belt) system. It serves as a guide for the drive belt, ensuring it maintains the correct path and tension while rotating around engine accessories such as the alternator, air conditioning compressor, and power steering pump. The grooved surface of the pulley is specifically designed to mesh with the ribs of the serpentine belt to prevent slippage and provide stable operation at high RPMs.

This part is primarily used in Mercedes-Benz vehicles equipped with V12 engines (M275, M285) and specific V6/V8 engines. Compatible models include:
