Does anyone know why the bolt on my water pump impeller keeps snapping causing my bike to use coolant? Is the pump seized and if so where do I get a rebuild kit?

  • Might need a new bearing behind it. Sometimes the older bikes get corrosion problems there. My 88 had that issue, the bolt was corroded and that in turn affected the bearing/seal behind it.

  • Ok cool thnx! I changed the bolt and firs up the bikes and the exact same thing happend so it probably is the bearing like U said hopefully

  • I think its a pretty common problem, it happened to my 91 model a few years ago
