I am wondering why the fluid underneath my radiator cap is neon green but the fluid in the engine coolant reservoir is blue?

All the newer Honda's I have seen have blue coolant. Did someone change the coolant on the car for some reason? If so maybe they put a universal coolant in the radiator. As long as it was a compatible coolant to your car then your okay.

It has been like that for three years, if it was not compatible I am guessing it would have showed by now?

I would think there would be some kind of issues by now.
