Oil cooler/heat exchanger
Posted: Wed Sep 11, 2002 12:54 pm
'Hello everybody,
I hope everything is runing well with your planes!
Right now, I am already thinking about next winter's maintenance session!
And I was especially asking myself on "how to clean properly the oil
cooler?"
Our Fairchild 24, ranger powered, as a right handside positionned cooler
looking like many (I should say every) american cooler, this big round
copper heat exchanger with by-pass valve here placed at the bottom!
(It seems to be the same on NA-T6, Stearmans, Staggerwings, etc...)
As some friends told me not to try any cleaning with current solvent or
cleaner (paint thinner, acetone,...), as I think it may be dangerous to
clean it this way without damaging weldings and letting a possibility to
make particles run away in the oil just after restarting the engine!
A friend of mine, who work as mechanics in the french air force in the late
40's until he switches to the french company Air France where he was flying
and maintaining Constellations, told me that they had a special machine with
pump and filters to make this kind of cleaning-rincing, as they usually let
the pump run a night, before reassembling the exchanger!
So, if any body does already make anything, let me know on the way you were
proceeding!
Or maybe, is it possible to get brand-new one, even from old stocks, or
making any standard-exchange???
Thanks for help! and tips!
