Brand new here and have a radiator question. 2002 Liberty. I’m replacing the radiator with an all aluminum. I’m trying to hook up the transmission cooler lines but the tubing bottoms out before I can catch a thread on the nut. It’s like the nipple on the radiator is too short, or the end part of the tubing is too long. Can I shorten the tubing a bit? There’s about 3/8” of an inch from the end to the collar. Any advice is appreciated.
