Radiator Cooling Fan Control Module: Testing and Inspection

1. Remove engine coolant temperature sensor from intake manifold.
2. With sensor's sensing end immersed in water, resistance should be as follows:
a. 32°F 5.8 Kohms
b. 68°F 2.4 Kohms
c. 104°F 1.1 Kohms
d. 176°F .3 Kohms
3. If resistance does not approximate specifications, replace sensor.
