Whining noises in my engine on 2003 Dodge Ram Van 1500

I have a 2003 van that as I accelerate my engine makes a whining noise like air is coming in someplace or as I asked my mechanic is probably being caused by the serpentine belt needing to be replaced or one of the pulleys the belt goes around is loose,what could the problem possibly be?

Hey Danny,
Sorry to see you didn't get an answer to your question. Were you able to get this addressed? Was there a problem with the drive belt or a pulley?
