Hey there, thanks for writing in about your 2005 Chevrolet Impala. You need to verify the cooling fan is cycling on to control the temperature of the engine. The fan motor may not be coming on. Have a mechanic diagnose the cooling system control for you to see if it's the cooling fan or if it's the control circuit malfunctioning. If the fan is coming on but it still overheats, then the cooling water pump may be not pumping enough coolant and need replaced. Have a qualified professional from YourMechanic come to your car's location to inspect the overheating problem firsthand for a proper diagnosis.
