Manufactured to OEM specifications, the Bare-Co B2004 is supplied without a pulley, allowing you to reuse your existing pulley where required. It includes a new mounting gasket for straightforward installation and is engineered to provide long-lasting reliability in demanding agricultural conditions. It replaces OEM part numbers 4131A013, 3641219M91, 3641832M91, and 3637411M91.

Common Signs Your Water Pump Needs Replacing
- Engine overheating
- Coolant leaking from the water pump

Replacing a worn water pump helps maintain correct engine temperature and protects against costly engine damage.
