6. COOLING SYSTEM UXV 500 Water Temperature Sensor WATER TEMPERATURE SENSOR Remove the center cover and gear shift of lever bolt Disconnect the water temperature sensor connector. Remove the water temperature sensor from the water joint. INSPECTION Water joint Connect the water temperature sensor to the ohmmeter and dip it in oil contained in a Water Temperature Sensor 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 temperature gauge with a new one. Temperature Standard resistance 50C 123.9478.9 Thermometer 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. After the water temperature sensor has been installed, fill coolant and perform air bleeding (refer to the "COOLANT REPLACEMENT" section in this chapter). INSTALLATION With thread lock applied to the threaded part, tighten the water temperature sensor. Torque: 0.8 kgf-m (8 N-m, 5.8 lbf-ft) 6-17
