12. COOLING SYSTEM K-XCT 125i WATER TEMPERATURE SENSOR REMOVAL Remove the luggage box Drain the coolant Disconnect the water temperature sensor connectors (1). Remove the water temperature sensor (2) from thermostat. (2) (1) INSPECTION Sensor Connect the water temperature sensor to the ohmmeter and dip it in water contained in a pan which is placed on an electric heater. Gradually raise oil temperature while reading the thermometer in the pan and the ohmmeter connected. If the resistance measured is out of specification, replace the Thermometer temperature gauge with a new one. Temperature Standard resistance 50C 133.9178.9 100C 2629.3 Handle the water temperature sensor carefully as it is vulnerable to impact. Do not allow the water temperature sensor and the thermometer to come in contact with the bottom of the pan. 12-16
