Radiator Cooling Fan Temperature Sensor / Switch: Testing and Inspection

1. Using a suitable ohmmeter, check that there is no continuity between the terminals when the coolant temperature is above 100°C (212°F).
- If there is continuity, replace the switch.
2. Using an ohmmeter, check that there is continuity between the terminals when the coolant temperature is below 91°C (196°F).
- If there is no continuity, replace the switch.
