Hello,
Had a weird coolant leak on 2008 Cobalt. Replaced some hoses, radiator had a slight leak so I replaced that as well. Kept losing coolant. Final found it. Where the metal pipe goes into the water pump there is a rubber seal. Replaced that and everything seems fine. Just wanted to share this as it isn't obvious unless under the vehicle while it is running.
