If the noise is coming from under the hood,I would check the alternator and waterpump.
You can do this by using a long screwdriver as a stethiscope. Hold the pointed end on the body of the alt or pump and put your ear to the handle.Remember, put the screwdriver on the body of the alt or pump...NOT on the pulley!!!!!! While the engine is running you can hear and feel where the noise is coming from.
