Do you have to drain coolant to replace sensor?
Do you need to drain coolant to change coolant temperature sensor? Open the radiator valve and drain about two to three quarts of coolant. You only need to remove enough to drop the level below the sensor.
How long does it take to change a temp sensor?
If you are doing it yourself it will take 4 to 5 hours. However if a skilled mechanic is doing it, it will take 2 to 3 hours only. Whether your car was running or not.

What causes a temperature sensor to fail?
Temperature sensor failures are common in cold applications when standard sensors are used. Why? Because the seals of most sensors are not designed to withstand the severe material contraction that occurs at low temperatures.
Where is the temp sensor located?
It is often located behind the front bumper, but on some vehicles can be found in the door mirror behind the glass. It is used to estimate air density and by the air conditioning system – the system will not function if the air outside is too cold.
What happens when temperature sensor goes bad?
The coolant temperature sensor can fail and transmit cold signals to the computer. This action confuses the computer and stimulates it to enrich the fuel mixture unnecessarily. This can cause the fuel mixture to be vibrant such that during combustion, the fuel can’t be adequately consumed within the chamber.
