#259 Inspection of water level sensor
• Remove the water level sensor from the radiator.
• Turn the starter switch ON.
• Dip the water level sensor in a container filled with engine cool-
ant, and check that the pilot lamp goes on and out under the fol-
lowing conditions.
Condition
When water level sensor is
out of the engine coolant
When water level sensor is in
the engine coolant
• If any fault is found, replace the sensor. (See Gr14.)
#262 Inspection of water temperature sensor
<For water temperature gauge>
• Dip the sensor in a container filled with engine oil.
• Raise the oil temperature to the specified one while stirring oil.
• Measure the resistance between terminals 1 and the body.
