HELP !! my car sounds like a dying goose!

On the way home today I noticed my car sounded like I ran over a goose and it was dying under my hood. SOOOOOO embarassing at the redlights. Can anyone tell me what MAY be wrong??? PLEASE

I would shoot the car! either that or open you hood and find the problem! next take off the serp belt and let if run for ONLY A FEW SECONDS! THE WATER PUMP WILL NOT BE CIRCULATING COOLANT AND WILL OVER HEAT YOUR ENGINE! Try to do it in the morning or after the car has coold all the way down! If no noise then it is a delt driven accesory!

The alternator will squeel...not ....Quack!?!? the Power sterring might be low so check that! You should be able to narrow it down!
