The engine coolant thermostat should be replaced if it is not functioning properly or as a preventive maintenance measure after a certain mileage or time interval.

An engine coolant thermostat is a component that regulates the flow of coolant through the engine to maintain optimal operating temperature.

In most cases, a malfunctioning engine coolant temperature sensor (ECT sensor) will not prevent the car from starting. The engine coolant temperature sensor (ECT sensor) is responsible for monitoring the temperature of the engine coolant and sending that information to the engine control unit (ECU). The ECU uses this information to make adjustments to the fuel mixture and ignition timing for optimal engine performance.
