I have for several years flown in cold and hot weather with Van's variable
shutter in front of approx. 50% of the radiator - see attached photo (the
photo was taken before I installed an oil thermostat, so I have no plates in
front of the oil cooler anymore). My 912ULS has 50/50 glycol/water, and I
have not experienced problems even on hot airfields. However, to be on the
safe side if flying much in hot summers, the shutter can be removed in 30
minutes for such seasonal flying, as this will allow more air to pass
through the radiator.
I purchased the shutter fra Van's Aircraft in the US, and the Bowden cable
with accessories from Aircraft Spruce.
