Losing coolant

[Gregory OConnor]

On a puke recovery/refill system, fluids 'displace' and move the
spring in the cap to relieve the expanded fluids never more than
7psi. Air in the expansion tank compresses and packs energy. a quick
rush of expanded fluid could prove 300 psi???? while opening the 13#
valve unless the energy first blowes a hose or compramised liner
seal apart. I just think there is a larger issue here if there is
such large selection of such a small variable pressurecaps
avaliable. from 3 psi to 15 and some half units.????????????

I wonder if deaeration is a Bluebird term (maby one of the
engineeres had a dairy) or if de-airing would even be an issue (or
necessary realtime manitenance task of the cooling system)if the
system was all hydrolic with a true puke tank??????????

that's because any air bubbles in the system will tend to eventually
rise to the highest point and depart from the fluid.

coolant is supposed to stay well below even the boiling point of
water, but rather just to keep the system "closed" under normal
circumstances.
