In a 2005 Beaver, with HydroHot, when I had it serviced, they put in the yellow, not the red, antifreeze/fluid. Is the yellow the correct juice??
When I had a Aquahot, in a 2007 Camalot, I used distilled water. That's what I was told to use.
Which is correct?? Thanks, the Muffin Man.

I would check with Aqua Hot. According to Roger Berke some of the Hydro Hot units did use regular ethylene glycol automotive antifreeze. If your unit previously had the pink GRAS (propylene glycol) antifreeze, it should be filled with that.

The green is poison if it leaks into your fresh water supply. I'm not sure how possible that is but it's my understanding that they changed to the red boiler fluid to avoid that risk. Mine came with the green and I had it changed to red boiler fluid. I will PM.

Apparently the older HH models had the fresh water line wrapped around the outside of the boiler fluid tank, so cross contamination wasn't possible, and they used regular toxic antifreeze.
Don't know if a HH installed in a 05' coach would fit into that catagory

I have a 2005 Safari Panther and mine uses the pink biller fluid. I just had to fix a leak caused by the plastic drain pipe and it took 8 gallons of biker anti freeze and 8 gallons of distilled water. I found it at camping world online for a great price compared to some places I looked both online and in stores.

When I had it serviced; filter, nozzle, check up, they found a small leak, fixed it, and put in "yellow" anti freeze. I was told the red and the yellow d not mix. Just looking for what to put in, I guess I'll go over tomorrow and get a gallon on Yellow, That is what is in there now.

Reading the manual, says to use 50-50 water and PG antifreeze, that's whaere I got adding distilled water to top off.

Sounds like the manual confirms you should have PG (propylene glycol) antifreeze. That is the red/pink GRAS (generally regarded as safe) coolant that will not poison you if the coil leaks and contaminates your freshwater system. If the shop put in ethylene glycol (automotive antifreeze), I would make them drain it, flush it completely and put the correct stuff in.

Century Fluids makes a GRAS coolant that is kind of yellow/green so they may have used that. In any case I would find out exactly what they put in to be safe.
