I put a Champion radiator, (three core and notched), but the transmission cooling lines need adaptors. I can't be the only one to do this. The steel lines, from Eckler's, are 5/16" with a female end. The radiator is 1/2"-20 straight threads inverted flare. The threads are not pipe threads. I have been looking for a couple weeks, on and off, and haven't found the right adaptor.

Any ideas, or what did you use?

Thanks, in advance for any and all help,
Kurt

Kurt, i just ordered my 2 nd champion. The 3 row notched arrived yesterday.

My 200-4r has the 1/2" male hose fittings.

I have a new 4 row showcars radiator, and it is brass fittngs for trans that have threads in th ID as well as OD.

What trans are you running, PG? Thoought those fittings were standard.

omarine,

I have a 700r4, but my problem is not with the transmission fittings, it is with the the aluminum radiator. I have my lines connected to the transmission, just need to connect the lines to the rad.

Impala62,

What brand is your radiator. The threads from that connector from Ecklers are pipe threads, at least that is my understanding. My threads for the cooling lines are 1/2"-20 straight threads. Would you be able to check your threads before you install it? If not, no biggie.

The radiator(GPI racing) has straight thread but I tried it and it fitted.
I installed it with some threadsealer and did not use to many force to install it.
It does not leak and is on the road for some time now.

Had to use what was available, very hard to find in the Netherlands.

Yeah, not helpful, and wrong threads to boot!

I used the picture as example! I don't know what ends you need. You only know that. I was giving you a idea of the fitting with the barb on it.
Yes it is the right threads for mine.

55 Brodie,

Thanks for the response, but that doesn't fit. On that fitting, the threads into the radiator are pipe threads not straight threads that I need. The other end of that adaptor fits perfect.

Andy,

My first post states exactly what I need, with the exact threads that I need.

Thanks,

Kurt, I expect you may already be aware that the quick and dirty fix would be to cut off the flares on the tube ends, replace the female thread nuts with 5/16" inverted flare nuts, and re-flare the tube ends. Is that fix acceptable to you?

If no, and you will not settle for anything less than the correct adapter, are the female thread nuts SAE flare (45°) or JIC/AN flare (37°)? If you don't know, I would hope that Eckler's should be able to tell you.

EcKlers won't have a clue. Even the small child who manufactured it in China wouldn't know either. Thats the problem when you buy offshore manufactured junk. If it where me I'd ask for my money back and buy a made in USA radiator the next time.

raycow, that is the fitting that I needed, and finally found. And no, Eckler's don't have a clue.

The part number for that fitting is C5880X5 from Eaton Weatherhead. It is Carbon Steel. I didn't even look for any other material. They may have it in SS or brass, I don't know.

SO, if you have a Champion radiator and steel 5/16" tranny cooling lines, this is the adaptor you need. You really don't want to force in NPT threads into a radiator with straight 1/2-20 threads.

Have a good day,
Kurt

Kurt,
did you replace the tube nuts and re-flare the cooling lines tp 37 degrees to use that Weatherhead fitting?
