Tensioner pulley for AC or Water Pump / Alternator Belt - Genuine BMW

Only for vehicles with Hydraulic Belt Tensioner assembly

These engines can have one of two different Serpentine belt tensioner assemblies for the main accessory drive belt. While there are some generalities in what BMW model may have which system, there is no way to fully verify which system is on a given vehicle without physically (and visually) checking the vehicle. You MUSTverify whether the vehicle has the hydraulic tensioner assembly or the mechanical tensioner assembly before ordering a replacement tensioner or tensioner pulley.”
