On another issue...does this drain tube leaking underneath, on the passenger side indicate a leaking heater core?.....

Ok I have no AC anymore. It was removed before I dropped in the engine. I looked inside the Bronco at the passenger side floor and don’t see anything.

Makes sense though that it is the heater core, since I just recently hooked it up after removing the bypass setup I had. Oh well, back to the bypass....

So is it possible to get heater core coolant dripping from it?

Yes.

This isn't the greatest pic, but here is the inside of my heater box.





My a/c evaporator is gone and right below where it sits is a small recessed hole in the center, underneath all of the leaves in my box. Behind the evaporator is the heater core, which you can see in my pic. If your core leaks it could run down below the evaporator and into that hole, which is above that tube in your pic. If it leaks a lot there's a good change it'll run past everything and leak out of your box and onto your floor pan. If you run your heater and have a leak in the core you can also have the coolant come out your defrost vents as a fine mist and coat your windshield to the point it looks like an oil spill where it changes various colors and you can't see out of it.

Yes. The heater and AC coil share the same box and pan. It is certainly the core. Lucky for you without ac you can access the heater core fairly easily.
you get to it completely from inside the cab. If you open the box under the hood you will be opening somthing not meant to be opened ever
Lots of people make that mistake. Including me

Thanks all! I put the bypass back on. I’ll get to that heater core later. Too hot and humid....
