Exclamation Radiator issues

I recently replaced the radiator in my 99 firebird and it didn’t come with a cap for the hole circled in red. The old one I had on the old radiator is cracked. This is causing my coolant to leak. My pops and I have searched high and low across multiple cities to find this piece and we can’t find it anywhere. We’ve been asking for a “radiator drain plug” but I’ve come to determine that’s not what we should be looking for. So I’m asking everyone here what’s this part of the radiator called and what can I search to find the cap for it. Driving like this could cost me my engine and I’m tryna keep my baby as healthy as possible

Exclamation Radiator issues

I recently replaced my radiator on my 99 firebird and the new radiator came without this cap circled in red and my old one is broken. I’ve searched high and low for a replacement but I don’t think I’m asking for the right thing. Can anyone tell me what this part is and what I should be searching for ?

when you say firebird you mean the 3.8?

I have 2 LS radiators from 4th gens in my shop at the moment they are both for manual cars but they dont have that port. You could try getting the v8 radiator and eliminate. Its dimensionally the same and the fans fit it, i did a ls swap on my 01 but converted to a manual so I just bought a ls radiator and used the same fans. hose outlets for the pump maybe slightly different
