Fan most of the time once she is warm is on high. No cords or overheating. I am thinking maybe the coolant temperature sensor. What is the sensor on side of radiator called? And can you confirm it does have one on this car? Even with the engine off ignition on first thing in the am fan goes on for 7-8 seconds then shuts off. Can you please tell me where the coolant temperature sensor is located? And it says online this is an n55 engine since its 2011 can you confirm?
