Radiator Cooling Fan Motor: Description and Operation
Cooling Fan Operation Hazard
To avoid the possibility of personal injury or damage to the vehicle, do not operate the engine with the hood open until the fan has first been
examined for possible cracks and separation.
Unexpected Cooling Fan Operation
The electric cooling fan will operate whenever the key is ON and the coolant is hot (above 97°C [207 °F]), even though the engine may not be
RUNNING. Avoid placing hands, clothing, tools, or other objects in the fan blades at any time. The fan blade will also operate if the engine
coolant temperature (ECT) sensor is disconnected.
DESCRIPTION
The engine cooling fan motor is controlled during vehicle operation by the constant control relay module (CCRM)(12B581), the powertrain
control module (PCM)(12A650), and the engine coolant temperature (ECT) sensor, which energize the engine cooling fan motor under the
following conditions:
^
When the engine coolant temperature reaches 10°C (221°F).
^
When the A/C is turned ON.
