Well I have finally solved the mysterious coolant loss after all these years. I'm not sure if we all have the same source of the loss but for it's worth on my coach, it was the hose clamps on the line that runs from the hurricane to the radiator pipe as well as hose clamps where the hoses from the front school bus pump attaches to the hoses that feed it. Being in Sub-Zero temps helps to identify these very minor leaks. Since finding these leaks and tightening the guilty hose clamps I have driven 2000 miles with no loss of coolant. This is a first in 13 years. The rear School bus pump was removed and bypassed years ago, and I will be removing the front one and bypassing it shortly before it blows out, which it will. I can only suggest that others that have this mystery loss go through and tighten every hose clamp in the heating and hurricane systems as well as the radiator etc.

thanks for the update. We also had 2 coolant leaks that were difficult to find. One coolant leak was in the bathroom along the floor where the hoses run. CC had put a small screw through the hose. Very small leak but took a long time to find it! The other major leak was atop our Hydro Hot unit and it was the clamp. The coolant wasn't leaking on the ground so we had no idea where it was going. Finally Lonny decided to check all the clamps everywhere. The culprit was on top of the Hydro Hot unit. The top of the unit has a lip around it, and it created a "pool" where the coolant was leaking. What a mess!! Since then, no more coolant loss.

One other point about clamps and connections:
We had intermittent slide problems and looked everywhere! Finally our brother-in-law came to help troubleshoot and they started at the back passenger side electrical bay and found that the wires were all loose where they screwed to the panel. If you check them make sure you turn OFF The batteries!! Ask me how we know that! LOL!
