Folks:
I believe the 912 series engines are primarily oil cooled, with some water and air cooling to help. The engine can be flown at reduced power for some time after a complete loss of coolant without seizing.
Before I sacrificed myself and my airplane, I'd fly to a safe landing area to fix the problem.

Hi everyone.
I think the experienced pilots amongst our community need to stop this right now and I don’t class myself in that group. Imagine the situation, say on take off, your busy in the cockpit to say the least and you see the engine temp rise into the red,
what do you do, you can’t shut down, you must expedite a safe landing asap. If you have time before the engine seizes try to do an abbreviated circuit and radio your intention with a Pan call and pray you can get back down in one piece. I am sure other pilots will offer differing scenarios. The point is if on top of the considerable work load the pilot has, he now has to somehow manage boiling water and steam in the cabin, he isn’t going to do it.
Sorry for being blunt.

When the fluid boils the cockpit could be filled with steam. That would
certainly get your attention!

Your 912 was designed to run at least 30 min. without coolant. Coolant only cools the heads and not the rest of the engine like a car. You can help control temps after total coolant loss by flying at reduced throttle settings. If temps exceed the maximum on the heads the you should have the heads tested for hardness.
