Coolant Thermo Sensor
- Remove coolant thermo sensor from water pump. Place switch in water with a thermometer and heat water gradually.
- Using an ohmmeter, check the resistance between both terminals as the temperature rises. Check resistance using COOLANT THERMO SENSOR chart. If any abnormalities are found, replace sensor.
