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.

SOURCE: coolant leaking from two russted
Having enough room to hit the new freeze plug to install it is probably your biggest problem They make an expandable freeze plug which tightens with a socket, but aside from a hot block, I don't know how close to the exhaust manifold your freeze plugs are. An emergency repair may be to drain the antifreeze, clean and scuff the old freezeplug and try JB Weld. If you have a small leak after that, some radiator sealer may finish the job.

Without knowing your car specifically I can suggest the generic way to do it. Locate the two heater hoses going into the firewall, probably on the passenger side. They're the ones that get hot and are about an inch + in diameter. Disconnect. Measure the inside diameter of the hose and purchase a short piece of galvanized or copper pipe (6 inches) at Home Depot. Connect both ends of the hoses to the pipe to form a loop. Secure the hoses so they don't land some place that would cause a problem.
I had this problem on an 85 Tbird. I had heard about a product called Bars Leak and tried it. It worked. No leaks and I kept my heater. You should be able to find it at any parts place at less than $10. Ground black pepper also has worked for me.

The core is bad. You're lucky you have a catchpan and drain in your car... most people end up with coolant all over their feet when this happens! You have a few options. 1. You can pick up a bottle of cooling system leak stopper (available at Wal Mart and auto parts stores), follow the directions and see if that stops the leaking. 2. You can cut the heater lines and bypass the core entirely (obviously this is only a good idea if you live in Arizona or some other warm place). 3. Replace the core.
