Procedure for replacing just the upper radiator hose?

[labatt]

So looking around the DIY stuff I see info on replacing the water pump, the radiator and other larger jobs.

I just need to replace the three hoses that comprise the "upper radiator hose". I have the assembly coming on Friday.

A significant amount of the coolant has already drained (onto the driveway) from the busted hose.

Can I, pretty much, just disconnect the old hose assembly and connect the new one in? Or do I need to disassemble and remove other parts of the cooling system in order to get access to everything and get the assembly installed right?

Sorry for the basic question... just getting into DIY, not very handy and want to be prepped.
