I am not yet flying so can't answer your query, but...
The so-called thermostat does not control coolant temperature (as does the
device
by the same name used in a building's heating and cooling system) but rather
it restricts coolant flow to the radiator when the engine is started from cold
so that the engine will get to operating temperature more quickly. Once at
the thermostat's set point temperature coolant flow to the radiator is
unrestricted.

Subject: Re: 2 items - service bulletins on Rotax and
Just wondering..... what kind of _coolant_ temps are folks seeing;
@cruise?
@climb?
@taxiing?
Is anyone out there measuring it?
I am asking the question with full understanding that it depends upon outside
air
temp (and speed/power setting) since there is no thermostat in the rotax
plumbing.
I would assume that the highest temps would be during a prolonged taxi.
In that case, are folks blowing coolant out the bottle vent when/if it gets
to over-pressure?
Cheers & thanks,
