As the teardown of my F650GS (R13) progresses I take a look at the water pump seals and impeller shaft. There is certainly something leaking into the coolant and making white gunk. Hopefully the engine has not been contaminated with coolant, or I am in for a whole world of pain. This is not my finest filming and I do waffle on a bit, when on a big project it makes me philosophical, so apologies.
