Engine Drive Belt - Serpentine Belt - 6Kx1155 - ContiTech OEM
This Serpentine Belt drives the alternator, water pump, and A/C compressor in many models with B46 and B58 Engines.
Fitment note: 530i/540i, X1/X2, or X3/X4 only up to 2019 model year (not for 2020+).
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.
