Product Details

This part cross-references AP Exhaust 30124 for the same application.

VAICO’s product line focuses on OE-style replacement components for European vehicles, making this pulley a practical choice when servicing BMW cooling system hardware on models such as the BMW Z3 and BMW 328i.

Common Problems This Part Addresses

  • Worn or damaged water pump pulley surfaces
  • Belt noise caused by pulley wear or misalignment
  • Improper rib engagement on a 6-rib belt system
  • Accessory drive vibration from an out-of-spec pulley
  • Cooling system service requiring OE-numbered replacement parts

Installation Notes and Tips

Verify pulley diameter, rib count, and mounting dimensions against the removed part before installation. Inspect the belt, tensioner, and adjacent cooling system components at the same time, since pulley wear often appears alongside belt or accessory drive issues. Confirm OE number 11511740512 when matching the application to your BMW.
