You talking about the two short hoses?
I did it once by very gently pulling the pipes out of alignment, threading the new hose on, pushing the pipe back and sliding the hoses down and over the heat exchanger feed pipes. I reused the clips too as I didn't want to use jubilees.
I've done them again since when I had to change the headgasket and had all the pipes off and fitted some slightly thicker, reinforced silicon hose.
