Symptoms of a worn coolant switch (sensor)

Coolant level sensor location
The coolant level sensor is fixed to the radiator tank (coolant reservoir, coolant expansion tank) where you refill your car with coolant.
It can have many shapes but modern electronic units look like a rectangular box.
This is shown on a Peugeot 5008 vehicle.
Start by disconnecting the electrical connector (last picture).

Removing the coolant level sensor
- You can only work on a cold engine
- Just tilt the coolant sensor by hand 90 degrees anticlockwise (first picture) to take it off (second picture).

Refitting the new coolant sensor
Push in the new level sensor then tilt it again 90 degrees clockwise and plug in the electrical connector.
Do not forget to mix and add coolant until the level is between the Min and Max marks.
Use a concentrate that you dilute with distilled water (not tap water) or a ready-to-use coolant.
That's it!
