The thermostat is broken. Is the engine fault light on?

If the thermostat is broken, the engine fault light will give an alarm: 1. Thermostat is to ensure that the temperature of coolant is within the appropriate range when the engine works under different load, speed and temperature conditions; 2. The thermostat controls the cooling intensity of the cooling system by controlling the flow rate of coolant and the flow rate of air flowing through the radiator; 3. After the thermostat is removed or takes effect, the cutting door will stop at the open position and cannot be closed, which will lead to the failure to quickly raise the temperature to maintain the normal working temperature of the engine during startup and accelerate the damage to the engine; I think brothers should consider the summer temperature in their respective regions and choose to install or remove the thermostat. In winter or autumn, it is necessary to ensure the normal operation of the thermostat.
