Radiator Cooling Fan Motor: Description and Operation
NOTE: Radiator cooling fan operation is controlled by the engine controller. The fan should run when the A/C compressor clutch is engaged or the
engine coolant temperature set limit has been exceeded.
Switching through the engine controller provides fan control for the following conditions:
1.
The fan will not run during engine cranking, regardless of engine temperature.
2.
The fan will run at vehicle speeds above 40 mph only if coolant temperature reaches 230°F and will turn off when coolant temperature drops to
220°F.
3.
At speeds below 40 mph the fan switches on at 210°F and off at 200°F.
4.
To help prevent steaming, the fan will run when ambient temperature is below 60°F and coolant temperature is between 100-195° with engine at
idle, for three minutes only.
