2000 Dakota V8 i'll try to explain this the best way i can. well when i first start my truck up it makes like a loud ' blowing noise ' and if u push the gas down it rpms high then something starts to Squeak but as u drive it for say 4 5 mins it goes away and it is back to normal. at first i thought it was my fan clutch but i replaced and it was not so im pretty much dumb founded. any ideas would be apreciated.

 

maybe another bearing on something is shot? maybe take of your belt and see if anything has play in it not sure what would cause it to come and go though. also another thing to try is to completely take the clutch fan off and see if it does it, you don't really need it anyways i just took mine off its worth a shot even though you just replaced it
