Trying to replace radiator and everything is disconnected but that one line. I cant figure it out and dont want to damage the line in the process. How does that fitting work that is connected to the 90 nipple.

Disconnect the negative battery cable at battery. Drain coolant from radiator Remove the front grill . Remove the cooling fan from the engine, if equipped. Remove the two radiator mounting bolts. Disconnect both transmission cooler lines from radiator. Disconnect the connector for the electric fan. Disconnect the power steering cooler line from cooler. Disconnect the radiator upper and lower hoses. Disconnect the overflow hose from radiator. The lower part of radiator is equipped with two alignment dowel pins. They are located on the bottom of radiator tank and fit into rubber grommets. These rubber grommets are pressed into the radiator lower crossmember.
You don't get there that way. remove the six or so bolts that attach the rail above the radiator to the front trim, and, remove the bolts that hold the same rail to the radiator and rail extensions from the front fenders (including latch loop) also remove the electric fan. once you get the top rail off remove the air box, lower hose and trans cooler lines. Radiator lifts straight up.
The cooling system is pretty much self explanatory hoses go from and to the most obvious places...(you wouldn't try to stretch the lower hose all the way across to the upper hose connection). The trans cooler in the radiator can actually be connected either way. It is non-directional, being a simple coil inside the radiator tank. If you want to install an external trans cooler, that's a bit different...it needs to go on the outflow side of the radiator so it can further cool what the radiator has already cooled down. An easy way to find out which side is the return line, simply take one fitting off the radiator, remove the coil wire so engine dosen't start and "bump" the engine over till trans fluid comes out. if out of radiator nipple you are on the correct side, out of hose, install on other side. Leaking lines can be partially replaced using brass compression fittings made for this. Only use them on straight clean runs, not on heavy rust or bends.
It has been too long since I did this work, but here is a tip: Go to Auto Zone, or one of those parts houses, and they will probably have a tool for this, I can't say for sure, but I believe it will be something to release the connection so it will come apart.
