Coolant THERMOSENSOR
- Remove coolant thermosensor from water pump. Place switch in water with a thermometer. Heat water gradually.
- Using an ohmmeter, check the resistance between both terminals as the temperature rises. Check resistance using COOLANT THERMOSENSOR chart. If any abnormalities are found, replace sensor.
