Leaking Transmission Oil Line Fix?

Hey all. I recently installed my new 3 row radiator from CSF and the where the upper transmission fluid line goes into the radiator tube is leaking. It seems that the hose does not want to go all the way on it. It is not leaking too fast, about a drop ever 2 seconds. I was wondering if I could use some caulk to seal it to stop the leaking. Will this take the heat of the engine and also will the oil eat through the caulk. Other options are also appreciated. Thanks.

Also, just wanted to say that I am not bashing CSF. It is not a problem with their radiator, but the hose and connector thing in the hose. The radiator has solved my overheating problem and does not leak (the other hose (new) is the cause of the leak, or the connector thing)

You need a new fitting on the end of the hose. The fitting seals by the flare that is on it so sealing the threads will not work.

Now if I read that correctly I don't see why you can not seal it. I would not use caulk...maybe RTV, I am a firm believer in the red RTV, as long as you clean the surface very thoroughly. But I would do it right and change the line out, or just the fitting. Make sure its not cross threaded or that its not in the radiator itself.

Just from experience, the only way it will seal is with a proper flare on the end of the tubing.

It's a compression fitting, pipe dope, rtv, caulk, teflon tape, may slow the leak but they won't fix it. . .

Not trying to get too technical on you but it is a flare fitting. A compression fitting works by compressing a ring around a tube to seal it against a fitting.

Thanks for the help. I guess Ill get some new fittings. Got the last ones at AutoZone. Should I go somewhere else for them?

The ones from autozone are just fine.
