Water Valve

[hedwards]

I am getting a minor leak in my cooling system when under load, haven't been able to diagnose it while idling. It seems to come from the water valve area at the front just above the HWH control system any ideas are appreciated

TIA, Harry

Few of us know your coach & chassis well enough to know what you are talking about. Or what the reference to the HWH hydraulics could have to do with a cooling system issue. Maybe another 2005 Mounainaire owner will recognize the area of concern, but you will have to give better clues for the rest of us.



What chassis do you have? What part of the cooling system is leaking? Radiator? Water pump, a hose, or ???

The area you describe , front above HWH , water valve , sounds like the Evans dash HVAC system's electronic water flow control valve ( Ranco valve ) I had to replace mine for a similar leak .

You'll want to confirm the area of the leak ; rent a cooling system pressure tester ; because the Ranco valve is not cheap , $250 USD when I bought mine 4 years ago.
