Hope that everyone is having a great time in Branson! Sure wish that we could have been there.

Anyway, now that a large chunk of the brain trust is in one place, I'm hoping for some info regarding the operation of the gate valves that control the coolant flow from the Webasto system.

In our Liberty, we have 2 gate valves marked "Auto heat in/out" and another pair marked "Coach heat in/out".

If the blood/alcohol levels allow, I would appreciate some comments as to the function (yeah, I know, they either allow or prohibit the flow of liquid coolant) and appropriate use of these controls.

Seems I had one valve leaking slightly at the valve stem, but a tightening of the stem nut appears to have solved that problem. I assume that they can be repaired as any other gate valve??

Thanks for taking time from the partying, er seminars, to give this some thought.
