What is this trouble noise

(2004 Kia Sorento)
in Aurora, CO on February 15, 2012
sound like the water pump is rattling under the hood and making a trouble noise, the car is not running hot or has any fluid leaking out. Appears as if the noise is coming from a lower pulley, I think it's the pulley that the belt rest on. I can see the pulley moving slightly as if it may need to be tighten.

cannot tighten, just replace if the rubber has worn out. could be some type of bearing but a shop will have to put there ear to it to give you an answer.
