Hi Ferg,
Actually, it is Rotax's intent that airframe manufacturers measure the
reservoir temp, not individual builders. The idea is to be absolutely sure
that the engine cooling system never allows the coolant to rise to
a temp which would ruin (anneal) the cylinder heads!
Of course, since Europa never did this test, it is up to you.
On the 912s, like mine, it was the paragon of simplicity to cut the
rubber coolant hose about two inches from the reservoir outlet
and use the Lockwood-supplied t-splice to place a thermistor in the
coolant stream.
The hottest common point in the coolant system is the reservoir, so
your measurement point must be as close as possible! A more
accurate system would put a thermistor in the coolant drain line from
each cylinder, but lets not go crazy here ;-)
