I don't have the flap system in place as we don't drive the car in cold weather. We don't like to drive it when outside temp is below 65% degrees.
This is a common misconception about the thermostat system and why a lot of people leave them off. Having it in place speeds the engine warming up to operating temp. It’s important to get all the tolerances in spec to reduce wear. Prolonging warm up time only increases the wear on your engine.
