Do you notice any leaks either by smoke or by wet spots on the engine?

The coolant level sensor has a floating magnet that indicates to a reed switch for level sensing. If the magnet becomes detached, replacement of the expansion tank is called for. It happens, I have had toreplace several due to this issue.
