Radiator leaking

Have an 02 S10 crew cab with a trailer towing package.
I have leaking from the right side of the radiator from the second connector down an oil cooler line. I have tighted the nut as tight as possible, am I missing a washer or o ring that I can replace to fix the leak? There is not other issues with the radiator so I would hate to have to change the whole thing out.

Any suggestions or help would be great thanks.

Re: Radiator leaking

It's not leaking oil, it's leaking coolant.

Re: Radiator leaking

A radiator shop would have to take the tank off to replace the seals. Should be under fifty bucks to repair.

If it's leaking from here...try tightening the lock-down nut. If that doesn't work, you should take it in to a radiator shop like Hoosier Rick said.

Re: Radiator leaking

So I took the lock nut off cleaned the threads reall well- cleaned the lock nut and bent the nut in a little bit, added an O-ring and some yellow pipe tape on and reassembled it and it is holding to this point. Thanks for all the input.
