WARNING: This page is about a different car, the 2019 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.
The electric thermostat is closed at temperatures below approximately 82°C (179°F). When the engine coolant temperature reaches approximately 82°C (179°F) the electric thermostat starts to open and is fully open at approximately 96°C (204°F). In this condition the full flow of engine coolant is directed through the radiator.
