So, I am going to have to drop the engine to put it back in?

You won't have to drop the engine.
With that said... I replaced my coolant tube with the engine in the car, but it's a complete pain in the posterior.
It actually mounts under the exhaust manifold, and kind of above and behind the A/C compressor.
The "hook" end of the pipe goes toward the passenger side of the car, with the opening pointed upwards. It meets the hose that comes from the thermostat housing.
You will need to remove the aluminum A/C bracket, and maybe remove the A/C belt and loosen the bottom bolt, to let the compressor tip forward.
You probably will also need to drop the exhaust system and maybe the starter.
Did I mention that it's a pain in the posterior? It's like the
entire car is assembled around that pipe.
I used every curse word in my vocabulary, and maybe coined a few new ones. The dog even left the garage.
But it can be done without dropping the engine.
Edit - Here is a picture of several tubes . They are shown right side up.
