country coach aqua hot -- boiler coolant?
The coolant level on my aqua hot is low (it is basically empty in the reservoir tank). Two questions: what coolant do i buy (it says it requires some special boiler coolant). I am hoping there is ...

Coaches made 2002 and older use regular engine antifreeze cut 50% antifreeze and 50% distilled water. These heaters do not have an electronic control board nor do they have a warning to use special antifreeze on the heater and on the overflow bottle.
Coaches 2003 and newer that have an electronic control board use GRAS (Generally Recognized As Safe) boiler fluid made by Camco. This bottle says ready to use but Aqua Hot states it should be cut 50% boiler fluid and 50% distilled water.
Once you have the proper coolant and distilled water on hand, purchase a 13# radiator cap at any auto parts store. Remove your radiator cap and discard. Cut the overflow tube off of the filler neck barb and cut the tube back about one inch. Re-attach the overflow tube using a hose clamp (hopefully the one that was there, if none get one). Do not stress the barb as you push the tube back on.
Now fill tank with the 50/50 coolant to the top of the neck. Install the new radiator cap and fill the overflow bottle to above the cold line. Turn diesel burner on and bring heater up to temp. Top overflow bottle to the hot line.
You do not need to drain and change the fluid, just top it off.
Annual service is recommended each 12 months and you are seriously over due. If the diesel burner runs, I will be pleasantly surprised.
