Radiator Cooling Fan Temperature Sensor / Switch: Testing and Inspection
INSPECT WATER TEMPERATURE SWITCHLOCATION: On the water inlet housing.
(a) Using an ohmmeter, check that there is no continuity between the terminal and body when the coolant temperature is above 93°C (199°F).
(b) Check that there is continuity between the terminal and body when the coolant temperature is below 83°C (181°F).
If continuity is not as specified, replace the switch.
