Radiator fans not working properly

Good afternoon,

With the key in the on position, remove the connector to the coolant sensor and see if the fan kicks on. If it does, the sensor is bad.

If it does not then we need to do some testing on the relay to see if power is being sent to the fan.

1. Turn OFF the ignition.
2. Drain the coolant below the level of the engine coolant temperature (ECT) sensor. Refer to Draining and Filling Cooling System (3.4L) or Draining and Filling Cooling System (2.2L (L61)) in Cooling System.
3. Disconnect the ECT sensor electrical connector.
4. Carefully remove the ECT sensor.

INSTALLATION PROCEDURE

NOTE:
Replacement components must be the correct part number for the application. Components requiring the use of the thread locking compound, lubricants corrosion inhibitors, or sealants are identified in the service procedure. Some replacement components may come with these coatings already applied. Do not use these coatings on components unless specified. These coatings can affect the final torque, which may affect the operation of the component. Use the correct torque specification when installing components in order to avoid damage.
Use care when handling the coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.
