I recently took my '10 Concours in to have the cooling system checked out. During stop and go traffic, the engine was overheating and it turned out that the right side radiator fan was seized up and blowing the fuse. The shop contacted Kawasaki and they stated that they did not consider it to be a manufacturing issue since there was evidence of a small rock being lodged in the fan. I recognize that the radiator is exposed, but the fans are on the back side of the radiator protected from the front wheel kick back. Does anyone have any similar experiences and am I right to consider that the fan should be replaced under warranty. (not that it matters in this case, but I have the extended warranty through 2017). Thanks in advance for any advice.
