Hi Dan, thanks for this. It seems there is an updated part number re the radiator that is fitted to the later ISF's. So 2008 to 2011 comes up with the following P/N: 16400-38210 and the 2011 to 2014 comes up with the following P/N: 16400-38211. Could it be that the later cars dont have the issue as it was addressed in the change to the radiator? I'm thinking if us pre 2011 owners can upgrade to the later radiator?
