Replacement radiator vs stock fitting. Steel line is spliced with rubber section and it’s not leaking but I would like to replace it. Stock fitting has tiny c-clip. I think they used a different style adapter. I don’t like the rubber repair portion but I don’t know if proper steel line will fit into the aftermarket radiator. ![image](https://global.discourse-cdn.com/cartalk/original/3X/9/b/9bb71b3f2adb3fa87fde5de3a622e1265727e42e.jpeg) ![image](https://global.discourse-cdn.com/cartalk/original/3X/d/b/db4dec1de60ee08a53b528ccd77c282f97326b02.jpeg) ---

Lots of calcium crud. I don’t know if a new cooler line will fit into this newer radiator without issues. This is stock line. The adapter line looks like it has a compression fitting? ---

found this fitting. I suppose my adapter will unscrew from radiator? Seems like a good route to make a mess. ![image](https://global.discourse-cdn.com/cartalk/original/3X/6/1/61a11c3c6d7337bb31a7e5725938acb210dce588.jpeg) ---

Those quick-connect fittings are for fast assembly, they can leak after time. I would be satisfied with the compression fittings. If you are worried about the hoses, replace them. Using hose isn’t necessarily a bad thing, some vehicles use a section of transmission hose near the radiator to deal with vibrations. ---

The rad hex is about 7/8”. I figure that’s just the way aftermarket radiators are built. So you have to use adapters to go down to 3/8 tubing. The bottom fitting has a tight curve and the rubber hose is kinked there. Enough to make me wonder if the flow is restricted. ---

Back in the 70s when everybody in our family was buying cheap cars with slant sixes, I used to strip them of parts before they went to the junkyard. Always had spare radiators on hand. I learned to never mess with those radiator fittings. I just cut them about 3" from the rad and used rubber hose. Much easier. Years later we went to 2.2 Mopar 4 cylinders. ---

I would get some Gates transmission cooler line on amazon and rerun the kinked section in such a way that it isnt kinked and call it a day. This looks like GM vehicle. ---
