i want to know which of the two cooling lines is the pressure line and the return and where they go on the radiator of a 1998 grand cherokee laredo

Not sure what box you have or why you want to or need to know which is the flow and return. Its easy enough to undo one and turn the engine over very briefly with suitable tray to see which is which. Do not run the engine or you will have a big mess.
