Got a '92 Protege. Radiator is leaking. Has a separate condensor in front with its own fan. Looks to be a simple pull out the old one, drop in the new one deal until I got to looking and see a line that runs into the bottom of the radiator. My questions are: What is this line go to, and What is the condensor for? Thanks

I've attached a picture of the condensor in front of the radiator, then one of the line going into the bottom of the radiator.

 

The condensor is for the Air conditioning. ** Do Not dissconnect**

I'm guessing your car is automatic as the arrow is pointing to the oil cooler lines for a automatic transmission.
