RE: Europa-List: Cooling issues, once again!

I run have run Evans from new, with completely standard installation and no
cooling problems.  Max OAT I have experienced is 28C.  I suspect some of the
problems with Evans have been caused by switching to it from standard 50:50
without getting rid of every last drop of the old stuff before using Evans .
The instructions do warn of this problem.

I have been following the cooling topic and wondered what the forum thought
about using Evans coolant?


I noticed Kevin uses Evans from his Death Valley flight description, but
Mike Parkin threw his away!


I am about to refill my radiators and was considering Evans as the way to
go. I am based in Colorado and expect hotter temperatures in the summer than
northern Europe and cooler ones in the winter.


I would welcome anyone's advice and experiences.


BTW - on my 912UL installation the Oil cooler was lowered and made a
dramatic difference - stable temperatures and no sign of overheating when
the aircraft was flying in the UK. I am considering lowering the Oil Cooler
for my 914 installation for the temperatures get up to the high end of the
scale during climb out, but do stabilize in the cruise.

You could be right there Frans. btw theory says that cowl inlet should be
much smaller than rad area so that some pressure recovery can happen, also
lips must be smooth.

Looking closer to both radiators, It appears to me that the oil cooler
has closer spaced fins, thicker fluid canals, and an overall smaller
useful area.
It might be that this is the reason why lowering the oil radiator also
