Engine Coolant Temperature Sensor - Repair or Replace
If your engine coolant temperature sensor has failed, you may notice one of several symptoms: your temperature gauge doesn’t move, your engine overheats without warning, your radiator fans don’t switch on, or they don’t switch off. If your 2018 Cadillac ATS has any of these symptoms, it's a good idea to let a trained Cadillac technician perform an inspection.
