Well as one example I experienced a sudden catastrophic engine failure this
year in my 1999 Toyota minivan. An engine cooling fan circuit malfunctioned
and the engine overheated while driving in a snowstorm. I pulled over right
away but nonetheless the engine block had melted and I needed a new block
and new cylinders... $8000 in warranty work repairing the engine due to
failure of a $125 part.

Hmmm, wait, you were driving in winter and the engine overheated
because the cooling fan malfunctioned? My cooling fan never comes on
in the winter. As long as I'm moving at any speed, the air through
the radiator alone is way more than enough to cool the engine without
the cooling fan coming on. It's only when I stop and idle for a while
that the fan may come on, and that only happens if it's relatively
warm (40 degrees).

Something isn't adding up.
