Daewoo Lanos whining noise in motor?

it may be your steering assist pump: check the liquid level and if it is low, add until it is close to 'MAX'.After having added the Power Steering liquid, turn your steering wheel all the way to the left,hold it there(you should still hear the whine), then turn it all the way to the right,hold it there and repeat until you won't hear it anymore(2 or three times).

PS: the power steering reservoir is not the one near the steering pump,that is the brake liquid reservoir; power steering reservoir is closer to the front of the car and has a bigger cap that says...power steering on it
