Heater core help
i just got home from work and steam started coming from the def vents. I can see anti freeze on the passenger side inside fire wall behind the dash, and also on the radius arm. I can't see were it came from to get the radius arm though. It's not a lot but I know this aint good. When I started the truck up again I could still see steam coming from the def vents and could see a little coming from the area where opposite that in the engine compartment(heater core area) along the fire wall. Please help, this thing needs to get me to work in the morn. It's a 93 eb w/351efi.

The heater core is easy to get out on yours. Remove the glovebox, then remove the plastic cover that's behind it (be kinda careful with the heat control cable). You'll then be able to see the heater core, and it'll be obvious if it's leaking. To complete the removal, undo the two hoses at the engine side of the firewall and work it out into the cab.
