My 2004 Trep just overheated and when I did a visual check, found it hissing/leaking from somewhere under the "upper intake manifold", drivers side. The coolant tank was completely empty as well. Before pulling the upper manifold to check, does anyone have any ideas on the cause?

Id fill it and verify the leak location first...the hiss may just have been residuial steam pressure. Usually the warter pump seep hole is the leak location.
