Coolant Sensors

BMW coolant sensors communicate vital BMW operating information to the driver. Whether your BMW's coolant level is too low or the operating temperature is too high, these sensors send urgent information so you can react as necessary. Because these sensors do wear out over time, we recommend replacement during any BMW cooling system overhaul to avoid false or missed information. Use our SEARCH BY MODEL feature to filter these items for your BMW.
