Crank Pulley V Belt 7Pk (Hajus) (M271) (Mercedes-Benz C-Class W203 / W204 / E-Class W211 / SLK-Class R171 / Sprinter) is designed to drive multiple engine components via the crankshaft in a range of Mercedes-Benz models. This part directly impacts the operation of accessories like the alternator, power steering pump, and air conditioning compressor by transferring rotational power from the engine.
This crank pulley V belt is specified with a 7PK profile, matching the original design used across several Mercedes-Benz vehicles, including the C-Class W203 and W204, E-Class W211, SLK-Class R171, and Sprinter models. When comparing to an old belt, check the number of ribs and length to ensure compatibility, as this determines the belt’s grip and alignment on the pulleys.
For buyers needing a replacement, focus on the fitment to the M271 engine variant that these models share. The Hajus brand indicates the manufacturer but does not imply OEM status. Use this listing to verify your existing belt specifications or consult the vehicle’s service manual to confirm the right part for your engine’s accessory drive system.
