trans cooler to radiator fitting

[chappys4life]

Finally got my 78 k5 blazer running but the top trans cooler line is leaking. I want to add a trans cooler anyways as I want to do some off-roading and help keep the transmission cool.

Its a th350 transmission with a champion https://www.championradiators.com/product/CC716 radiator. On the site they claim Transmission Cooler Included (1/2" -20 STRAIGHT THREAD).

I am trying to find a barb that screws into the radiator then provide a 5/16 barb so I can go rubber line from radiator to trans cooler. I am struggling to find a fitting, I called summit and they could only find a npt fitting which seems to big. What is the correct fitting?

If you don't have your add on cooler yet, they normally come in the kit. To answer your question is 1/2 flair/tubing fitting

Awesome, found a dorman fitting that match at O'Reily. Will try it out tonight. Yeah you are right I probably should have waited, the b&m is in route haha.

I've just used a 5/16" brake tubing section and put a bubble flare on the hose end instead of hunting for fittings..some carbs used the same 1/2" x 20 thread with a flare like the brass one pictured..
Pays to keep these kinds of trinkets when you scrap or swap parts from your trucks..saves much time hunting for them "new".
