The 37011P uses a one-way clutch design rather than a standard pulley, and the DriveAlign line separates decoupler pulleys from one-way clutches because they are not interchangeable. For Mercedes-Benz E300 applications, this part number 37011P matches the specified fitment and requires the listed installation tool for proper service.\u003c\/p\u003e\u003cp\u003eThe Gates 37011P is a practical choice when replacing a worn alternator decoupler pulley on a Mercedes-Benz E300.
