7-10 COOLING AND LUBRICATION SYSTEM
ENGINE COOLANT TEMPERATURE SENSOR
REMOVAL
• Lift and support the fuel tank. (6-3)
• Remove the frame head covers. (3-3)
• Disconnect the engine coolant temperature sensor coupler
1.
• Keep the motorcycle upright.
• Place a rag under the sensor and remove the engine coolant
temperature sensor 2.
INSPECTION
• Check the engine coolant temperature sensor by testing it at
the bench as shown in the figure. Connect the temperature
sensor 1 to a circuit tester and place it in the oil contained in
a pan, which is placed on a stove.
• Heat the oil to raise its temperature slowly and read the col-
umn thermometer 2 and the ohmmeter.
• If the temperature sensor ohmic value does not change in the
proportion indicated, replace it with a new one.
 Temperature sensor specification
If the resistance is noted to show infinity or too much different
resistance value, replace the temperature sensor with a new
one.
