Hey guys, I’m replacing the transmission cooler line on my 2006 Ford Fusion 2.3L automatic (L4) and I’m running into an issue with the radiator fitting side. The new cooler line is basically identical to the old one, but when I try threading it into the radiator/trans cooler port, it only goes in partway before getting very hard and wanting to cross-thread. The weird part is that even the original OEM line started doing the same thing when I tried reinstalling it after removal. The tube itself seems slightly offset from the radiator fitting, so I have to push the line sideways a bit just to get it started. I attached pictures showing the offset and how far it threads before binding. Does this look like damaged radiator threads, a bent cooler line, or is this normal with these Ford compression-style fittings? Also, what’s the proper solution here before I destroy the radiator threads or damage the new line?
