It is your heater core. I fixed mine for $144. Ordered the new part on Ebay and followed these instructions http://www.volvospeed.com/vs_forum/index.php?showtopic=9717 It was very simple, I'm a middle age grandmother! The hardest part was cleaning up all the antifreeze. You will need a shopvac, a small one is $20 at WalMart.

check closer to just underneath the firewall--it could be a smaller problem than a heater core--Ford 4.6--5.4 engines have a tube just underneath the intake manifold that the rubber hose goes bad and it will leak towards the back of the engine.Lets hope so-what i hear its very expensive to change a heater core in an Expedition.

You can bypass the core or fix it that's up to you but I would change or remove the thermostat first. If it still overheats then start looking at the water pump and radiator. Hope this helps. Good luck.

two things--first replace your cabin air filter.second reverse flush your heater core with a garden hose and that should remove the build up of material in your heater core and restore the flow,hope this helps
