This part is listed by BMW as BMW part number 11288650740 (11 28 8 650 740) and is described as the main water pump & alternator serpentine belt for B46D, B58C, and B58D (B58TU) engines. It measures 6PK x 1,153mm. As a preventative maintenance plan, we recommend replacing the Serpentine Belt every 40,000-60,000 miles. The extent of damage from a failed belt is worth the extra cost every few years.
Fitment note: not for mild hybrid system (energy recovery system, option 01CE).
This is an OEM B58 belt manufactured by Continental - the original supplier to BMW for this part, as well as many other belts and rubber parts. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
