Pretty simple and straightforward question - Do I need to bleed the system after replacing the upper radiator hose, or do I just top it off?

I would replace the fluid you lost by replacing the hose and bleed the system. Shouldn't take all that long.

In this case, fill up the tank to max, idle the engine with heater on, fan on, then crack the bleeder until no air then close. Top off the tank.
