Yup, spring clip. By threaded fittings, i meant the actual piece that has the clip in it. They weren't pre-installed on the new rad.Originally Posted by Gregorius
Rad was checked over before install. Went ahead and put on fan/shroud before dropping it in all as one piece.
Crawling under the car and looking, its definitely coming from the flare/clip-ring area. Is there supposed to be an o-ring in the fitting before pressing the line in? Posted thread on r/mechanicadvice as well, was advised missing o-ring most likely culprit. New rad did not have any with it, forgot to check old one before scrapping it.
ATF shows overfull while cold and off as well, was told to pull out excess with a pump and line fed down through dipstick tube.
