At what temperature does the BMW thermostat open?

[NorahRose]

There is no standard opening temperature. The electronic thermostat is controlled by the DME (engine control unit), which determines when to open based on various parameters, such as: ambient temperature, engine coolant temperature, cabin heating temperature, electric water pump speed, transmission oil temperature, etc. Location of the BMW thermostat: The thermostat in BMW vehicles is located at the lower right side of the engine, near the water pump. Introduction to the thermostat: When the coolant temperature is below the specified value, the refined paraffin inside the thermostat's temperature-sensitive body remains solid, and the thermostat valve closes the passage between the engine and the radiator under the action of the spring, causing the coolant to return to the engine via the water pump.
