I am losing about half a gallon of coolant roughly every 1500 miles, or over about 3 months of running the Hurricane while camped. Not sure if it's caused by the engine running or the Hurricane. I suspect the latter but I cannot say for sure. I have searched from stem to stern for evidence of leaks. Can I find thing. In fact, I can release the radiator cap after a month and the the system is still pressurized. Oil analysis shows no coolant in the oil. I've checked the radiator and all the hoses. I've checked all the Hurricane hoses, pumps, front School Bus pump (rear was long ago removed and bypassed) everything. Someone told me that there can be coolant evaporation from this brass air purge thing for the hurricane system up high in the engine compartment. Has anyone else experienced this mysterious problem?

Hey Rich, while parked in Park City this past winter I used the Hurricane a lot for the first time. Before I left, I had to add between 1/2 to 1 gallon of coolant. My search revealed a leak at the MP pump in the Hurricane compartment. I replaced the pump, fittings and short stretch of hose going to and from pump.
Had the front heater MP circulating pump replaced by CC about 6 months ago and I just recently did the rear heater circulation MP "school bus pump" bypass and topped off coolant.
We'll see if I have the same loss while running the Hurricane a lot in the future Interested in what you find.

Keith, when you said you omitted the "school bus pump" in the rear, I thought that only pumped fluid up to the dash heater from the engine. This it has nothing to do with the Hurricane (or the loss of anti-freeze used by the Hurricane).
Right?

John,
Yes, the "school bus pump"/rear MP circulating pump at rear of coach (circulates coolant forward for dash heat and the other one up front pulls it forward...) up above the front of the engine is a separate circuit from the hurricane as far as I know but it is another source of potential coolant loss if it is leaking.
Rich is having this spurious loss and I had a loss temporally related to a time I knew I was parked and running the Hurricane a lot in winter. I was just going over a check list of things I had done in both coolant circuits to eliminate possible losses from either. Both circuits are supplied by our motor/radiator coolant....

Thanks all. Keith, there are no leaks from either of my MP Hurricane pumps. The rear one is sitting right next to the hurricane unit clearly visible and there are no leaks. The other one is sitting in the electrical bay where the inverter is in the little room in the back of the third compartment and if there was the slightest leak it would be noticeable. So I am still baffled.
John, I am referring to engine coolant: With the CO 45 Hurricane I have, the engine coolant circulates through the Hurricane. There is no boiler fluid. This model does not heat domestic hot water other than through the "engine assist" tube welded to the outside of the Atwood water heater

Wrong John, the engine coolant, the dash heater and the hurricane are all linked together through various hoses and fittings on this coach.

Yahoo Message Number: 115683 (http://groups.yahoo.com/neo/groups/country-coach-owners/conversations/messages/115683)
OK...but why is there a different antifreeze used in the Hurricane bay (I was told to use non-toxic)? I thought that the only time the engine's antifreeze became a part of the Hurricane is the loop from the engine to the Hurricane (to heat the domestic water from the engine). Then the non-toxic antifreeze is circulated through the hydronic heating system (the 3 fans in the coach).
So then, there are 2 antifreeze loops....one for the engine, dash heat & Hurricane and the other for circulation through the coach.
Is that closer?

John everything goes to the stainless steel expansion tank with the radiator cap on it, is the best I can explain it. When the engine is running the engine coolant circulates from the engine through the hurricane and to the dash heaters. When the engine is off the engine coolant that's in the hurricane system circulates to the expansion tank and to the heater inside the coach. My CO45 does not have any expansion tank of its own. There are other models of hurricane that do. There is no place to put boiler fluid in to the hurricane. If you somehow figured out a way to do that once you started the engine the engine coolant would flow into the hurricane system and mix with the boiler coolant. In this system there is no reason to use non-toxic coolant anyway since it's impossible for engine coolant to get into the domestic water system.

I've been in campfire conversations where the differences between Hurricane and HydroHot loops thru the engine and OTR Heaters has almost become rowdy:)! It's easy to confuse the two...
Rich - I have HydroHot, with the engine loop for both pre heating the engine, and arriving in camp with a hot tank of water. But one thing common between out coaches (Besides the rear bus pump that I too have bypassed.) - are the registers/heat exchangers.
I had noticed an increase in boiler fluid usage. Check all of my loops, hose clamps, HydroHot radiator cap, etc. I could find no problems. I finally borrowed a friends radiator tester, and add some pressure to the unit while cool - just to see if it was leaking. I confirmed that I had a loss of pressure. So the hunt continued. Found the the front register heat exchanger (On our coach, just in front of the passenger seat, above the step well.) was leaking. It was a loose clamp.
So if your heat exchangers with the Hurricane are similar to those in the HydroHot, you might want to check the heat exchangers. (Vern Burns at then OMC, now I believe at Marathon, told me to always check both the hose clamps and the heat exchangers themselves, for leaks - when unexpected and determined coolant leak took place.
Your unit will have a different odor, so good chance you'd have some sort of odor from a light coolant leak. The boiler fluid, was not much of an odor at all... (Of course, my DW has to tell me when a shirt should be sent into the laundry - so I might not be the best judge to that:)!).
Worth a look, and best of luck to you,

Thanks Smitty, I will investigate. I use Rotella ELC coolant which is bright red so it's hard to miss a leak although I suppose it could be evaporating from the Heat exchangers. I have looked at all three upstairs, and let's not forget the two in the wet bay, and I can see no liquid. How would I pressurize the hurricane system?

Rich, I have virtually the same coach you have. (2002 Magna) I experience the same thing as you but to a slightly lesser degree. Mine drops about a quart every few months. Oil analysis is clean. With a system this big and complex it may be impossible to find. Some say the hoses allow a very slow migration of fluid through the membrane. If you ever figure it out let us know..

I was told by my Hydro Hot tech, it's the hoses CC installed that carry the fluid. They are the only ones he sees this issue with.
The hoses allow water to evaporate, but leaves the coolant behind. If you continue to add the coolant, your mixture will be way off. He advised me to cut the coolant with water and add as needed and not straight coolant. Test coolant mix annually. He has a special device to measure the coolant to water ratio.

As I remember from talking to friends the earlier Cat engines were known for consuming oil either by combustion or leaking to the ground. 3208 was particularly bad, a C-12 not so much. But I know nothing about the C-10. TWInsall Jr 2004 Intrigue 11731 with a DAWG engine, that doesn't use oil.

That's very interesting. When I used to run regular green heavy duty coolant there would be a smell in here when the hurricane was run. Many people have had that problem. Since I converted over to red ELC, I no longer detect a smell. I find it difficult to believe that the hoses would allow just the water to evaporate without any of the chemicals in the coolant but it sounds like a good idea to look at the concentrations as you have raised.

I have a C12. That somehow the engine is burning this up without having a bad head gasket or ending up in the oil, etcetera, has definitely occurred to me. It is definitely not dripping to the ground. I would see it. I'm going to be traveling 700 miles or so in the next few days and I'm going to keep an eye on whether this appears to be the engine or the Hurricane to the extent this is possible..

The C10 and the C12 are the same engine with different displacement.

Follow up question for you sir. Do you have silicone hoses anywhere in the system? Heater hoses, or radiator hoses? Silicone will allow H2O to work it's way out of your system. This is how our HydroHot loses it's coolant, needing top off from time to time.

Check and make sure their is no coolant in your tranny fluid indicating a radiator replacement. It could also be the rear pump that sends hot coollant to the front dash is starting to fail. The smaller hoses that run from the top of the engine to the coolant tank and into the radiator may have started to fail. Other wise it maybe just the porosity of the hoses used in your coach.

It is my understanding that the Shell Rotella ELC is ethylene glycol based. This is poisonous if it gets into the water system and a no-no if you have pets. You should be using a propylene glycol based boiler antifreeze, such as Camco 30027, available at RV supply houses or Amazon.

I am just now catching up on the posts to this group. I have the same Hurricane system you have and I was also having to add fluid often. I had a leak in some "Y" valve at the front of the coach where hoses came together. Sometimes I would see a small amount of fluid on the ground, coming from that valve, but if parked on gravel or some similar surface I could not see the fluid on the ground. This was one of my problems with fluid loss.
Seems like the other leak was due to the radiator cap on the expansion tank. I replaced that at some point.
Since fixing these two items I have not used any additional fluid in a few years.
You will need to determine if the loss is from running the Hurricane or from running the engine or both. Both systems use the same cooling loop but I think the engine creates more pressure on the system.
I was having to add coolant but not the half gallon every 1500 miles as you are having to. I was loosing about half of that amount.
I know you said you still had system pressure at the expansion tank cap but a weak cap will still allow fluid to leak out under pressure and probably evaporate before you can see it.
It is very possible to have a leak somewhere that evaporates before hitting the ground due to the hot engine.

Thanks Richard. Where do I find this Y valve at the front of the coach? What does it look like? If you can direct me I will check it for sure.
As far as the cap is concerned, years ago I did have a bad cap and you are right it can evaporate but if you look carefully it left slight deposits on the outside of the stainless steel tank. I don't have anything now. if it's going past the cap into the overflow hose it goes into the overflow tank. I did discover 6 months ago that indeed that hose was leaking at the bottom of the overflow tank for quite some time. I replaced the hose tightened the hose clamp and that solved that problem but not the mysterious loss.

Yahoo Message Number: 115885 (http://groups.yahoo.com/neo/groups/country-coach-owners/conversations/messages/115885)
Rich,
It's been some time since I fixed the valve so this is from memory.
It's about 5" long and a "Y" about three inches wide. One end with two hoses and the other with one hose. Not sure what it is there for but the clamps on mine needed to be tightened and it was not easy to reach being that high up. Your frame is probably different than mine. I saw the valve when I was under the coach and looked up. It was high up about the level of the floor and in the area under the right side of the driver seat. I sometimes saw a small amount of fluid on the ground after running the Hurricane. That gave me some idea where to look. If you have the small leak that I had you will see it at some point. I don't know if the leak was occurring with the engine running or not but I think the system uses the same hoses for Hurricane or engine.
I was having to add about a gallon of fluid in 5000 miles so no where as bad as your leak.
With the rapid loss you are having I would suspect it's with the engine running and it's evaporating. If it were due to the Hurricane I would think that much of a loss would show up on the ground somewhere.

I would pressure test the system maybe up to 16 lbs and see what happens. Check your transmission fluid at a lab, to see if any coolant is leaking or being cross contaminated by a failing radiator. C-12 are not running a little warm in CC, so maybe you should install a temporary over flow catch tank. All my issues were a combination of failing radiators and San Danfaus cooling fan controllers.

Some of my coolant loss was from that valve and I could see a little spot on the ground. It's been some time ago but seems I only saw the spot when running the Hurricane.
Someone mentioned testing the system at 16 lbs. That should help you find a leak. Using one gallon every 1500 miles is a lot of fluid loss and should be easy to find. Keep us posted.

I only mentioned the 16 lb. test that someone else wrote to try. I have never tested a system but it should produce results with the amount you are having to add. I don't think the test requires much pressure. If it holds pressure I am not sure what you would check next.
If I were to do one I would read up about how to do it and one of the parts houses probably has the tool you can rent. Think about how they pressurize a new home plumbing system for leaks. You would have to understand what the pressure limits are for various components. I should think the radiator fins would one of the weakest components in our systems.

Hey Rich,
I just replaced my overflow plastic catch tank with Dorman 603-001 recommended by another CCer as a near exact replacement....the original one was always dry even after I added to it. Figured it was leaking.
On the replacement, I drilled out the bottom drain hole slowly (stepping up drill bit size one at a time) to one size shy of the 13/64 Dorman recommends when using tank for radiator overflow (tore the first one up drilling straight away with recommended 13/64).
Anyway, 1/4" ID hose fits on the Dorman overflow but the big square metal tank has what looks like a 3/8" hose nipple.
The plastic overflow tank I removed also had 1/4 barb yet the hose that was hose clamped on it was like 3/8" ID.
So, I figure I was losing coolant where the 3/8" ID hose was clamped down on the 1/4" barb.
Ordered some HPS silicone 1/4" ID and 3/8"ID height temp heater hose and a brass 1/4" to 3/8" barbed connector so I could step down the hose ID between big metal tank and plastic overflow. Might want to check and see if you have the same situation. Probably not the source of your loss but maybe some.

Folks after all these years I believe I found the mystery coolant loss at least on my coach. I would attach a picture but I don't know how to do it since I find this Yahoo platform to be the most challenging of any on the entire internet. There is a metal t-fitting coming off the big metal pipe that comes off the bottom of the radiator. There was coolant dripping off of this fitting without a doubt there is a leak. The bottom hose is a green hose that goes over to the other side of the engine and attaches to the hurricane system. There is a red hose coming off the top. I am not sure if it is the lower metal fitting that the hose attaches to which threads into the block which is leaking at the actual metal threads or the hose clamps which I tightened up. I will watch it. It's been quite cold here in Montana and perhaps this is why it's never dripped onto asphalt before unless the engine is running and it could easily have evaporated.

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!
