Bruno, you were right, the lines I had in my hand were to the 18 radiator on the manual cars. So it is the 3 radiators you already knew about, the 15-17, the 18, and the 19.
The 18 radiator, a MALE elbow goes into the FEMALE radiator port.
The 15-17 are the inverse situation, and if badhabit says the 19 is also the same port, then i believe him.

so... the 19 stock lines from the chin cooler to the 19 radiator, should fit the 14-17 vettes. Too bad they don't have those lines listed in the online parts catalogs

before i spread more wrong info, i realized i may still be getting it wrong...
is it possible the 18 and 19 have thicker radiators in the automatics, and a slightly thinner radiator in the manuals?
So, it would be like this... 2014-2017 radiators all the same on all c7's (not sure if that is true, if z06 are any thicker than base stingrays)
and then the 2018 and 2019 manual trans is the slightly thicker
and then the 2018 and 2019 autos are the thickest. (if not, please correct me, but i have a feeling the 19 manual radiator has those different ports if it is the thinner one like the 18)
IF that is the true way it works, then i brought this up because then the manual trans radiator 2018 and 2019 have the different hose with the MALE elbow that plugs into the FEMALE radiator port.
For people who have a 18 or 19 manual, if they upgraded to this AUTO radiator, they would need to be aware they will have to swap out the hose from the aux chin cooler up to the main radiator, as its fittings are different, and the 18 hose i had in my hands, its all 1 piece down at the aux chin cooler, it has quick connects, its a custom, formed GM hose. I think the elbow could swap from that hose however, so it would be a 60 dollar FEMALE elbow that needs to be bought also with the thicker 19 auto radiator.
I'm not trying to split hairs to be difficult to save face here... im trying to save someone a massive headache who does this swap and finds out they don't have the correct elbow (which takes days to order in because its a specialty fitting, assuming they find the part number (ill post it when i find it again))
I'm back to not being convinced that the 17's don't have the hose and male fitting i'm speaking about. Maybe its a typo/error in GM's computer, but this is from the dealer, and hose #9 has a MALE fitting on its top line which plugs into the FEMALE radiator port. It is a specialty hose, not a normal rubber one, I have held it in my hands, it is form fitted and black braided in sections, with permanently attached quick connect ports down at the aux cooler
Can people with a 2017 and 2018 and 2019 MANUAL TRANS z06 confirm what fitting attaches into the radiator at the top on the drivers side? Or get some photos of what the hose looks like down at the aux cooler. That will allow me to know which hose and thus which fitting is on their radiators.
otherwise people are going to hate us later when they find out we misled them, and their car is torn apart with no coolant in it for 3 days, while they look for an elbow that ONLY GM sells.
it is a male fitting at the top of #9
And here is the female fitting they are going to need, i have one, but forget and cant find the part number, which makes me mad because it was a nightmare to get it, took us over an hour looking in the computer one day at the parts department.
If anyone needs this elbow, i will sell it, they are like 70 bucks from GM. This is the elbow you WILL NEED at the top of the 19 auto radiator. 17-19? manuals will not have this elbow already on the car according to the parts computer.

How thick is the original radiator core ? The 2019 m7 radiator that x25 pulled out is 1 3/8" while the 2019 a8 radiator is 2 1/8". If I remember correctly I measured my 2015 core at 1" even. Tom Dewitt said it was 26 mm so yeah. Close enough.
There's a mistake somewhere in your research.
X25 just upgraded his 2019 m7 radiator to a 2019 A8 radiator. No hose changes required.
This is now a 2015 manual and a 2019 manual upgraded to the new radiator as a direct fit. I can't answer for my friends 2017 auto that started this conversation since it was installed by a shop. But he went from 2017>2018>2019 radiators.
Here's my theory:
2014>2017 all same 1" radiator.
2018 a8 has the 1 3/8" radiator.
2019 A8 has the 2 1/8" radiator.
2019 m7 has the 1 3/8" radiator.
Why they didn't go with the thick radiator on all models of z06 is beyond me

agreed, ill be the first to admit we still have no clue which radiators are in which cars... my main point here is, this is not a plug and play radiator for all cars, they are going to need the plastic elbow i have pictured above if they have the custom lines on at least the 2018 manual trans cars, and it is a nightmare to get (and according to the computer, its all 17-19 manual trans cars... which tells me the 17 manual trans cars have that radiator too... but maybe the computer is wrong? Either way, i know i have held these other lines in my hands, and they do not have the correct female elbow on their ends

We will go with... It's worth the purchase, be prepared for a little customization. However, it's been verified to work on a:
2015 manual z06 + added aux cooler.
2019 manual z06.
And I'm soon going to prove it with a 2015 manual with no aux cooler when I get the car I'm buying.
not trying to argue with you, but i think you might be wrong on the 19 manual... i think it has the male elbow. x25's pictures show he had a much thinner radiator, so i think his car was an earlier year car
im not sure he had a 19 manual he might have just been making a comment that the 19 auto is thicker than the 19 manual

alright... so now back to my original post... there's AT LEAST 4 radiators
2014-17 (with the female elbow and male port on the radiator)
2018 (with the male elbow and female port on the radiator)
2019 manual (with the female elbow and male port on the radiator)
2019 auto (with the female elbow and male port on the radiator)
so now the question, which one accepts the "male fitting"...
we know its not the one that ends in 29, thats the big dog. (interesting to see it is on some of the 18's)
According to your list, one of the cars from 2015 to 2019 has to have the radiator that accepts the hose #9 i pictured in my above posts with its male fitting on the end.
My gut is, you are missing 1 more part number.
(also, not sure why i thought c7 started in 2014 with their base stingray, i guess i thought there was a year gap until the first z06 came out, so take 2014 out of the mix)
The fitting is GM # 23171715 Lists for 73.16 (Damm)
To the best of my knowledge this fitting is used on every car that uses the GM EOC brick and/or the aux cooler.
Correct, i was not exaggerating when i said it is 70 bucks. Thank you for finding the part number for us.
But, onto your second comment...
how could it be to "the best of your knowledge" that all cars with aux coolers use that female elbow fitting, when i linked the diagram of the lines from the aux cooler, to the radiator, with the male elbow fitting, and when i told you i have held those lines, ordered into a chevy store, in my hands, and have seen it is a male fitting on the top of #9 hose in my drawings, on the real hose in real life with my own eyes, not a female?
And every car ever made with an LT engine in it has the cooler brick Tom... so...
you pretty much just said "GM made lines with a male fitting for no car ever made, just for the fun of it"
...for instance, your 2017 descriptions, you say (corvette without performance package (i assume you mean without aux cooler)
and then you say (corvette with auto trans and convertible and performance package)
okay... so were is the (non-convertible with performance package)? or the (manual with performance package)? you are missing at least 1 category.
The only other option on the table is, GM makes custom lines that fit NO CAR EVER BUILT, and shipped these pointless lines to our dealership service department, and put a diagram in the parts guy's computer of the lines that fit no corvette ever built... showing these pointless lines attaching the non-existent make-believe main-radiator to the aux chin cooler...
...just to screw with us...
and cost us to-and-from-shipping, and also cause customer's cars to be delayed in service departments... which only costs GM more money if service is under warranty?
See what im saying?... They have to fit A CORVETTE RADIATOR.
I have held them in my hands, i am not going off of what a paper says, im going off what I physically saw in real life. They make a male fitting for a female ported radiator... which they also must make.
There are at least 4 radiators, one accepts the male fitting
only 2 options on the table here.
People need to be warned before they tear apart their cars, they may need the elbow you linked before commencing the swap.
