Oasis fluid consumption

Just bought a new to me gently used 2011 DutchStar and it has an Oasis system. The fluid appears to be vanishing from the reservoir. There is NO leaks anywhere that I can see outside the coach.

Had it at the "cold fill" line, ran the system for a period of time and the res is very low. Not sure where to even start to hunt with no visible leaks.

It's not been run in forever and very low hours. Could there be air in the system thats caused the fluid level to decrease?

It could have been repaired or had the fuel filter replaced and is self bleeding the air out. I think I would refill and see if it finally stabilizes.

Kind of what I was thinking too. Gotta track down some fluid locally now.

We have a Hurricane heater which is the predecessor of the Oasis. It's possible that air bubbles are coming out of the system, but my experience has been that if you're losing fluid then you have a slow leak somewhere. Tighten all hose clamps you can find!

I had the same thing happen with my 2012 Ventana. The problem with my system was a leak of fluid in the burner box. When you would look in the sight glass on the box you could see condensation which was caused by the fluid leak. Ended up having to have the system replaced.

I just took the Oasis cover off and though it's not wet inside the box, I can see evidence of a leak with fluid residue inside. Great!

I would suspect it is leaking somewhere. I had a similar event. The Oasis fluid was down a little every time I checked it. I could find no signs of leaking beneath the coach. Newmar factory service checked it and found a loose hose clamp below and behind the washer. Once tightened, no loss in fluid.

It might be leaking only when the system is hot and under pressure.

I did find a leak the other day after posting at one of the fittings. I crawled in the basement compartment on the opposite side of the Oasis so I'm looking at the back of it now. Where the lines come off the back of the unit, I saw a drop of fluid leaking. Not fast at all, just a drop, but when under pressure I'm sure it's worse. Anyways, when I touched the crimp clamp of the hose, it squirted. So that hose clamp ain't quite doing the job. Going to get a regular automotive 1/2 clamp and double up there and should fix me up. Looks like that's the only spot I could find.

Where would the lines actually go that carry the glycol fluid, those aren't routed through the heat exchanges IN the coach right? That's just hot water going through those or is the glycol going throughout it all?

Glycol is the fluid that is carrying "heat" to all the heat exchangers in the coach. It's a better heat transfer liquid than is water and it's antifreeze so it doesn't freeze easily in cold weather.

OK, that's what I thought. So is it really just going from the reservoir to the oasis and back? 2 lines, one coming, one going?

I think the Oasis is more complicated than my Hurricane, but that's how my unit works. It is one continuous loop; the fans are controlled by thermostats in different zones, but the fluid circulates throughout the entire loop.
