I have this noise comming from one of the pullies i have allready replaced the altinator and the battery thinking that the altinator might be having a hard time to charge but it wasnt that and it only seems to do it when i first start it up in the morning but once i run it for about 7-8 minutes it goes away does any one have any ideas??? Please help!!!!

 

replace the belt and belt tensioner. It could be the a/c pump, but the noise should go away if the a/c is turned on.
