                                                 Water Temperature Sensor
 WATER TEMPERATURE
 SENSOR

 Remove the right side body cover and right
 footboard (refer to the "FRAME
 COVERS" section in the chapter 2).

 Disconnect the water temperature sensor
 connector.
 Remove the water temperature sensor from
 the water joint.

                                                                             Water joint
 INSPECTION

 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.
