MXU 500
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.
INSPECTION
Connect the water temperature sensor to the
ohmmeter and dip it in oil 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
temperature gauge with a new one.
Temperature Standard resistance
50ºC 123.9–478.9 :
100ºC 26–29.3 :
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)

Ɣ Handle the water temperature sensor
carefully as it is vulnerable to impact.
Ɣ Do not allow the water temperature
sensor and the thermometer to come in
