Chassis heat problems

[sfedeli3]

Hi Don,

Yes, the handle would rotate through to the open and closed stops,
even though the gate was staying closed. It's important to have the
valves for a couple of "foreseeable" issues- a tire blowout that
damages the heater lines, which run pretty close to the tires, a
failure in one of the heater cores and lastly, so that you can drain
the engine without draining the heating system in the event of working
on thermostats, water pump, etc... I put a couple of large aluminum
pans under the coach and just removed the hoses on the valves. This
allowed me to catch almost all of the coolant (which amounts to around
10 gallons for this job). I then re-filtered and re-used it. Most of
the air will work its way out of the system over the course of a few
weeks. I was able to re-fill the system with all but a few gallons
initially and kept topping it off until everything that I had captured
was gone.
