Can anyone tell me how to remove heater core on 83 f 150? I have
replaced several in my time, but all were done by removing glove box
and taking out bolts. this one has no bolts on inside firewall and I
see no way to remove from outside?

Behind the glove box is the plastic box-shaped plenum. The heater core
is behind that cover. Cover is held in place by 8-9 small hex-head
screws. The core has no attachments and is held in place by the
heater-hose clamps on the engine-side of the firewall. That is the
procedure on the '81. The '83 should be similar.
