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. Allan Bagley 86 westy

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.
