Heater core
neverthless I just replaced the heater core in my 98 Eddie Bauer 4x4 Expedition
what a marvel of packaging and compression engineering..!
like changing the coils or plugs, so simple a caveman can do it.
if they can find them under all the other junk the fomoco managed to squeeze under the hood.
I was surprised to see the Fomoco still used vacuum in 98 to operate the ac plenum and such...
but I cant complain, truck is past 160k miles and its been darn good.. all in all..even though some of it is a PITA to work on.
