I just changed over to Final Charge OAT coolant based on this thread, and the fact that the dealer couldn't confirm what they put into the coach in 2018 when they installed a new radiator. From a preventive maintenance perspective, should I put a coolant filter change interval on my calendar? While I know that the filter is "blank," I assume that means blank from a chemical perspective and not from a filtering perspective. As such, I was thinking of replacing the filter (I only noticed 1) annually, perhaps?
