I had the bypass tube like Tracy’s for a
while, not I just have a Schrader valve in that front top hole. A small amount
of air can get caught up there, especially in a taildragger. I think it will
eventually purge itself, but I just depress the valve anytime I have opened the
cooling system until coolant comes out.

Plumbing Questions...
I have two plumbing questions (for now
:) )
1. Can I
put a plug in hole on top of the engine at the front? I believe Tracy has
put an elbow fitting on his and then run 3/8ths inch hose to the high point on
the water pump "tower" (for lack of a better term). I'm not
sure if this is required to help "burp" the system of air or not but
the prior builder flew it with a water temp / pressure sender in the hole so it
is tapped already.
2. Is there
a good way to reduce the 5/8ths inch hose that will be required to exit out the
bottom of my Volvo coolant pressure tank to the 3/8ths inch size that is coming
out of the high point of my system (at the cap on water pump housing? I
have spend quite a bit of time "on-line" searching for something to
use and haven't been able to discover a suitable fitting yet.
