I have a rotating mass sqeaking noise comming from the lower radiator region ( i assume considering i don't have a stethoscope). Now im pretty damn sure it ISN'T the fan belt nor pulleys considering i just put on a new belt and underdrive pulleys. It isn't the fan because it only makes the noise when my engine is cold. ANy ideas? im open to suggestions 
EDIT: All bolts for pulleys are tight and belt has 1/2 inch flex in each lateral direction-aka normal
