Detailed Product Information

The Hella 009107841 coolant temperature sensor monitors engine coolant temperature and sends the signal used by the vehicle’s engine management system and gauge circuit. Accurate temperature feedback is important on Mercedes-Benz 190E, 300E, 300SE, 300TE, 400E, 500E, S-Class, and SL-Class models because the sensor data affects how the system reads engine temperature during operation. This part number 009107841 is specified with a 4-pin connector, NTC sensor type, and M14x1.5 thread for the listed fitments.
