I'm not sure but I think I've got it. Terry's info on how to loosen the first nut and then the hose nut seems to have done the trick. Haven't tested it yet because I'm in the middle of replacing all the hot water hoses on the engine and back to the auxiliary heater. The heater hoses are pushing 17 years old, and I don't want to fill the inside of my coach with hot coolant, nor dump all the coolant in the highway without knowing it. I'm also adding shut-offs to the send and return hoses for both the dash heat and the auxiliary. I'm putting them at the engine so I can cut them off in the warmer weather saving both unnecessary heat inside the coach, and the potential of a leak. I appreciate the info on the flair fittings. Hadn't even thought of that, but if this repair works, I'll save examining the fitting for another leak . I appreciate the advice.
