Engine service was 31-03-04 and first sign of a problem was 07-06-04.
Now having stripped the pump, I realise that to go through the process of stripping it and then not to replace the impeller is ridiculous - in fact the alloy and plastic washers can't be removed without at least some deformation, and more likely destruction. So I don't believe the impeller was actually checked at all.
