Do you mean the Hydro Hot system?..If so, CC techs at the recent rally, along with the Hydro Hot folks, told me that the CC factory is not purging the systems completely before shipment on new coaches.
Therefore, if there are no leaks anywhere, then it probably is the system purging itself of air and using up the antifreeze that's in the reservior. It seems to fix itself over time and if you are using the engine heat function it makes it occur sooner.
I've checked all my heat exchangers and I'm parked on cement, so I'm pretty sure mine doesn't leak. They also seem to think that if you have a leak that you can smell the anti freeze.???

Anyway, I'm in a wait an see mode, but truth is mine has used less and less over time.

Hope that this is helpful

I have a theory about the fluctuating coolant levels. My Hurricane shows empty in the reservoir in the wintertime, and I add fluid. Low and behold, when the weather gets hot the reservoir fills all the way to the top and I have to drain some out. It would seem this has to do with the fluid contracting and expanding with ambient temperature---what else could it be? But, then, why doesn't it fill up while operating since it is heated by the boiler? It will be interesting to see if the Hydro-hot shows up as being over-filled this summer.
I finally filed this problem away with the mystery as to how bugs splatter on the inside of the coach armor--and please don't tell me I'm backing up too fast.
