Yes, but they don't overheat because somebody set the wrong combination of
three different knobs.

What part of "so no overheating possible" didn't you understand? That
statement is simply factually incorrect.

What part of "not possible" didn't *you* understand? Frankly I don't
know abot the Thielert, but with the FADEC controlled engine *I* fly
regularly (a non-certified engine which isn't sold in the USA), I've not
been able to overheat it, and I *did* try. (Actually I've just tried to
reach the allowed limits, of course.) So yes, it's a reachable goal.

You try letting the coolant out?

That would definitely make it easier!

Only you would think of doing that. ;-))

Well, the manufacture hopefully would, but being German they would probably
say "this cannot happen"

So, are you saying that the FADEC will command a reduction in engine
power to reduce heating as the high-temp limit is approached?

I'm not absolutely sure on this, but I don't think so. I think it just
has an extremely efficient cooling system (overkill, so to speak) which
is regulated by FADEC, i.e. reduced to keep the engine temperature high
enough.

Of course I believe that if one really tries, one *will* find a way to
kill the engine. E.g. the POH forbids a sustained power setting of more
than 75%. Or, as others have pointed out, remove the coolant before
flight. Or if nothing else helps, take a sledge hammer.

Drain the coolant and go flying. Tell me how long the FADEC prevents
the engine from overheating.

Yawn. Dry the oil and go flying.

So, you finally admit that the FADEC can't prevent overheating.
