CAR ----------> 1989 Ford Escort SITUATION --> Low coolant light on, but coolant level ok
-----------------> in both radiator and overflow tank. QUESTIONS:
A Google search tells me the sensor is in the overflow tank. Is this correct? I've never had this happen before in any car. Is this a common problem? If I replace the sensor and still have the problem, I guess I have a problem elsewhere?
TIA for any advice.
