Did you end up jb welding the hole? I bought this f150 truck recently and notice that there was a deal right above that area were a hose should have been connected so looked like whoever had it before rerouted the hoses so I put them back the way they were supposed to go and out came antifreeze from that hole you were talking about jb welding.. I have no idea what it is either.. Thinking about just rerouting the hoses back to were they were before which basically cuts off the water supply so that it doesn't come out of that hole/plug area.. If I were to guess it has something to do with the heater core why it's apart of the manifold I don't know..

Well when all the hoses are in there correct places coolant comes out of that bottom plugged hole.. So not sure how to fix that other then plug it with something like the other guy on this discussion suggested jb weld or whatever..

The bottom hole in the throttle body? The coolant lines to the throttle body are just to keep it warm, kinda like carb heaters on light aircraft.
I don't really see the point of that setup anyway... a carburetor has a venturi, so I can see ice forming in there, but a throttle body is straight thru so... I dunno.
I disconnected my throttle body heater and everything is fine, but I live in the South where it's warm and I'd prefer my intake temps to stay low if possible. Maybe if you're where it freezes there could be a problem... doubt it though.

Just bypassed it altogether.. If I remember correctly instead of running that hose to the throttle body I just rerouted it back were it goes back into that heater core hose if that makes sense.. the heater hose that runs to the throttle body starts at just around or below the distributor area and goes to that top hole on the throttle body and then I think another hose runs out of that bottom hole back into the main heater core hose rerouting the coolant back into the main flow of things, so I just ran that first hose that runs to that top hole straight back into the system bypassing the throttle body all together.. you've got to reroute that hose that goes to the throttle body back into the system some how or your going to have coolant going everywhere.. I guess you could do it a couple different ways but sense that nipples there on that heater hose it makes it easy just to run it there.
