 |
|
On my recently acquired Kitfox 3, I decided to replace
the coolant with DexCool (who knows what it had!)
I pulled the cyl head vent tube and found that the
metal nipple where the 1/4" tube plugs on the RADIATOR
side of that vent tube is CLOSED.... it was NOT drilled into
the inside of the metal neck just below the fill cap?
Shouldn't that nipple be open to the inside of fill cap neck?
It's not an obstruction - it simply was never drilled.
I hope my question makes sense, thanks!

Yes it should. It's used to vent any vapor accumulation in the head,
either by inadequate bleed during fill, or through boiling when hot.
Sounds like an easy fix.

Wild;
THANK YOU for your post. In preparation for test running and first flight in the spring I have recently filled my 582 with coolant. After seeing your post I checked my vent fitting and....... it was not drilled either. My filling cap unit was supplied to the previous owner by Denny in 1989 ( Model II, Ser. 483). I wonder how many others are out there that are not venting properly, or how many other have had overheat problems without knowing why. This probably only applies to Model I and II but my recommendation is... check that the fitting is indeed drilled out.
Thanks again for you observation.
Cheers
Ken
