The point is all thermostats/housings/cooling systems pass some coolant when
the thermostat is in the "closed" position. Let me restate this in a simpler
more direct fashion for those having trouble with the concept. Coolant
always circulates when the engine is running. How much circulation depends
on the speed of the engine and the state of the thermostat.

If this was so, I would wonder why so many thermostats have a tiny bleed
hole. Not much point if they are never closed on any car.
