[C320-list] Broken Impellar

[Kurt R. Budelmann, M.D.]

I opened up the water pump to replace the impellar and noticed one of the vanes is missing.  I could not get to the heat exchanger to open it and look for the missing vane.  What is the best case scenario and the worst case scenario if I don't do anything?

I have the 3YM-30 Yanmar engine.  Does anyone know how to remove the alternator to get to the front of the heat exchanger?

Thanks,

Kurt
