If you find the coolant is flowing, it means the thermostat valve is open.
Why does my engine coolant keep disappearing?
A reservoir is under pressure in normal circumstances in order to increase the coolant’s boiling point. In case of a faulty radiator cap, the required pressure fails to build up inside the system, leading to overheating. When this happens, the coolant is likely to simply burn-off rather and disappear.
