Cooling leak

[JVinOlathe]

1999 Expedition 5.4 EB. I notice some coolant leaking under the car; upon inspection, I found this leak by the manifold where a hose attaches to a metal tube. The hose appears to be in good shape and the leak appears to be on the rusted angled metal tube (red arrow).
My question is, what is the name of the part with tubes where the hoses attach? (yellow arrow). I appear it could be the big hose assembly with 2 tubes where the smaller hoses attach (green area).
How do I remove the part? does it attach to the manifold? Is it just a pressure fit? The video shows the leak; would this be a candidate for JB weld? Thanks in advance for your help.

I understand that this part of the throttle elbow. What I need to know is if I can get just the part in the red frame without having the buy the entire throttle elbow assembly. Looks like the tubing with the right-angle screws into the round assembly; perhaps just this tubing is available?
The other option is to sand the tubing with the hole clean and use JB weld to temporarily patch the hole. The cooling system works at 16 psi which is not really high.

Update: I checked the JB Weld and they did not think any of their products would be effective; they suggested cutting the right-angle tubbing and attaching the hose there with worm clamp. since pushing a straight hose around the right-angle tubing might weaken the tubbing.
I found a part that is a piece of coolant hose with a 90-degree bend. I cut apiece of it, slid it over the 90-degree tubing using a little bit of lubrication and used worm clamps to fasten the hose to the tubing. Seem s to be holding fine so far.

I suggest you go to a junkyard and replace it like for like. You could also cut the elbow tap and thread an npt or straight nipple fitting. You can also jb weld it, after cleaning and sanding any corrosion off. I recommend you replace your coolant. It is severely rusted
