Replaced Radiator, but no heater hose hole!!

[TACOTRUCK247]

Hey! First time poster, first time working on a truck.
Just replaced the radiator on my Chevy R20 w/ a 7.4 454, but the new radiator doesn't have a hole for my heater hose.
How do I connect it back to the water pump and engine? Just an adapter? But where? In between the lower hose, pump to engine? Here's the current hose set up. Kinda want a quick fix (not removing the other water pump bolt) so I can get it to my buddy's shop for other work.

That fitting on top of the water pump. Next to the bypass hose. Should be 3/4 inch.

Thanks for the reply!
So take out that bolt and put in a fitting??

Yep I believe it's a 5/8 pipe thread plug. A decent hardware store should have a pipe thread to hose barb fitting.

Idea: take the wrong radiator back and make the seller get you the correct radiator??

This could work, but may not be an option for Eric.

Either hose routing will work.

There’s more to it than rerouting the hoses. Since it’s obvious it’s not the right one the next question is if it’s the right size.

I wanted to upgrade the radiator to a fan combo. I don't THINK griffin had that option?
