Default radiator issue

I am trying to see how I should run my radiator hoses due to an issue I have with my radiator.

The nipple seen in the picture below that is capped off with the black cap is broken off.. The hole has been sealed but I am seeing high temp issues.. I do not think it is an issue with the thermostat because the coolant is bubbling pretty good after it warms up.

I am unsure what this nipple that busted off is for.. I believe it is for the steam tube.

Oh this is a fresh motor..

The picture is just used for reference of the radiator.. Its a fourth gen radiator used in an unknown vehicle.. This is the best picture I could find that showed the nipple that I discussed in the first post.




Any information on this will be appreciated..

Thanks!

That fitting is indeed for the steam tube. Not having it connected is muy bad. You can always have a fitting brazed into the radiator tank.

Is there a way to run the steam tube into any other way? Such as putting a T hose that runs somewhere else?

Maybe because it's a reverse cooling system it was designed for the internals of the radiator is different? Is this thing for Drag only cuz a cooling fan would help out a lot...

You could tee it into another hose, but it would need to be one that the flow is going to the radiator.
