A coolant temperature sensor is an electronic sensor in a motor vehicle that indicates the temperature of the coolant in the vehicle. A malfunctioning coolant sensor negatively impacts the function of a vehicle's engine.
A coolant sensor helps keep an engine functioning properly by indicating the current temperature of the coolant running through the engine.
If the temperature of coolant in a vehicle gets too high, overheating of the engine may result. If the coolant temperature sensor in a vehicle is malfunctioning, replace it immediately.
The coolant temperature sensor gauge is located on the instrument panel in most vehicles. If the indicator is in the blue, the engine is at a safe temperature. If the indicator on the gauge is in the red, the engine temperature is too high.
Not all vehicles require the same amount of engine coolant. Make sure to read the owner's manual for your vehicle, before adding coolant or replacing the coolant temperature sensor.
A properly functioning coolant temperature sensor helps to extend the life of your vehicle's engine.
