Engine Coolant Temperature Sending Unit - Repair or Replace
If your engine coolant temperature sender 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 1998 TOYOTA AVALON has any of these symptoms, it's a good idea to let a trained TOYOTA technician perform an inspection.
