connector thread on champion radiator (1 Viewer)

[workingdog]

I'll champion tomorrow, but can anyone tell me what thread size the transmissions cooling female threads are on a champion radiator. Since there aluminum, I don't want to assume the size and trash the threads. Flared fuel line threads in beautifully, but the fuel line is too small. What can I thread in that will have a 90 and barbs or AN or push/lock?

Usually a 5/16” inverted flare, which is 1/2x20 thread. Earls sells the adapter to AN from there. I just did this on an LS swap for my son’s square body.

To clarify, I adapted to -6, which is 3/8” line.
