Radiator Cooling Fan Temperature Sensor / Switch: Testing and Inspection
When performing the following test, refer to Fig. 3.Fig. 3 Cooling Fan Component Locations:
Using an ohmmeter, ensure there is no continuity when coolant temperature is above 93°C (199°F). Ensure there is continuity when coolant temperature is below 83°C (181°F). If neither check is good, replace temperature switch.
