My thought process was that if the resistor is open circuit causing loss of the slow speed, the temperature would rise to 112 degrees C before the fast speed was triggered. If, for whatever reason, the fan is unable to lower the temperature then the pressure relief valve in the expansion tank cap might open and expel a large amount of coolant.

The test is easy and quick and will answer your question.

Recently a member's car was filled with a very low concentration of antifreeze on the understanding that some work would soon be carried out requiring draining. The best laid plans are susceptible to change and that's what happened. Unfortunately time passed and the overnight temperature dropped below freezing. I think you can guess the rest.
So the answer to your question is: how self-disciplined are you?
