Still having problems. It seems all of my valves are open, but I'm not sure I'm looking at all of them. I can't seem to figure why any would have gotten closed. I ran the engine and turned the webasto on. Still cold air. I'm going to try to burp it. It would make sense that there might be some air in the system. I just had the coach serviced at Marathon, Coburg, and Al did change the coolant filter. Guess I'll poke around a little more. How can I be sure all valves are open? Righty tighty, Lefty, opens it up, right?

Any other suggestions are certainly welcome. It is getting cold.

Thanks,

Adam
