Customer Questions
When to replace the engine coolant thermostat?
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.
What is an engine coolant thermostat?
An engine coolant thermostat is a component that regulates the flow of coolant through the engine to maintain optimal operating temperature.
Will the engine coolant temperature sensor keep the car from starting?
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).
