Hi,
In the middle of last year the water pump was recently replaced on my XCh (as a preventative measure, no leaks beforehand) and at the same time the radiator was removed to be cleaned.
A couple of thousand miles or so of TET later, there is what I'm 99.9% sure is coolant leaking from the hole between the water pump seals, implying that the coolant side seal has failed. The expansion tank is almost empty of coolant. I forget the brand of coolant used to refill but it's pink and I recall magnesium friendly.
Whilst riding the TET there was no sign of overheating.
Given the pump shaft, impeller and seals were new and as far as I know OEM, I'm baffled as to what could be the cause of the failure. Could the leak be caused by a pressure build up itself caused by another component failure? Any ideas welcome.
I'm hardly relishing the thought of removing the swinging arm, frame component et al. to fit a new pump and seals, especially if it has to be done again in the new future if the root cause is not established.
Thank you,
Ian.
