Is a Thermostat a temperature sensor?
The Thermostat is a contact type electro-mechanical temperature sensor or switch, that basically consists of two different metals such as nickel, copper, tungsten or aluminium etc, that are bonded together to form a Bi-metallic strip.
How to replace a coolant temperature sensor on your Radiator?
Once you’re radiator has been drained, make sure to replace your drain plug or reinsert the petcock before proceeding. This will ensure you don’t forget to complete this step before adding more coolant once the coolant temperature sensor has been replaced. Step 7: Remove electronic harness from the temperature sensor.
Can a corroded coolant temperature sensor be a warning light?
Certain makes of automobile do not have an engine temperature gauge on the dashboard, and in these vehicles, the engine temperature is indicated by a warning light once it becomes too high. A corroded coolant temperature sensor will give an incorrect reading.
Why is the coolant temperature sensor so important?
The temperature readings taken by the coolant temperature sensor are important, as this information is responsible for adjustments to the vehicle’s fuel mixture, which is necessary for optimal functioning of the engine and for operating the engine’s cooling fans. Coolant temperature sensors are prone to corroding over time.
Can you change the coolant in a radiator?
Although you may have collected the radiator coolant when you drained it from the radiator, it is highly recommended that you add new coolant. This will ensure that the coolant temperature sensor will work correctly. Add new coolant, mixed with distilled water as recommended by your specific vehicle manufacturer.
How do you replace a coolant temperature sensor?
Position the coolant temperature sensor in the engine block. Tighten gently, as over tightening will damage the sensor and cause it to give faulty readings. Plug the electrical wiring into the replacement sensor.

What should coolant temp be when engine is hot?
With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm.
Can a bad coolant sensor cause a car to not start?
Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.
