Water pumps, particularly Japanese water pumps, are durable over the longer term, but will eventually wear, especially if tap-water (!) has been used rather than the recommended coolant - modern coolants are generally water free.
If you are reading this then you will probably already be working on, or about to start work on the refurbishment of the pump.
Below are other parts, that in some cases will have to be replaced, seals and gaskets for example and other components you may require:
Add as many components as you wish to the same shopping cart, new O-ring seals 670B1508670B2016 and bolts 120P0625120P0616 for example, and still only pay the same single fixed price shipping cost.
Pro-workshop gasket sealant 08C70K0234M to complete the job like a professional.
This component may have other applications within the Kawasaki model range.
