At Shady Bend/Tracy Crook's this past Oct, I looked at all the rotary
installations that had flown in.  I liked what Jim Mosur (spelling?) has
done:  He has his 2 evap cores in series - water flows from left core to rt
core - in the hose that connects them right over the prop shaft, he
installed a drain valve like at bottom of an older radiator.  The valve is
at high spot in system - open it while filling and the air goes out of both
cores out the the valve that opens upward.  Can't get much simpler than this
if your cores are up high.

If you have them mounted lower, you can just put a small hose from a T in
place of Jim's valve and run the hose into bottom of your expansion/header
tank.

  Thanks for the procedure Ed.  I had figured this would be one of the times
that the EWP would come in handy, since you can circulate water without
running the engine.  Since the water won't be heating, and expanding, I
should be able to run it until all the bubbles are worked out of the system.
Still hard to believe air will flow downhill to get out of the evap cores
though.
