Engine Coolant Temperature Sensor
If your engine coolant temperature sensor has failed, you may notice one of several symptoms: your temperature gauge doesnt move, your engine overheats without warning, your radiator fans dont switch on, or they dont switch off. If your Subaru has any of these symptoms, it's a good idea to let a trained Subaru technician perform an inspection.
