Radiator Cooling Fan Temperature Sensor / Switch: Testing and Inspection

INSPECT WATER TEMPERATURE SENSOR




Using an ohmmeter, measure the resistance between the terminals.

Resistance:
Approx. 1.53 kOhms at 80°C (176°F)
Approx. 1.18 kOhms at 90°C (194°F)
Approx. 1.03 kOhms at 95°C (203°F)

If resistance is not as specified, replace the sensor.
