How do I replace the coolant overflow hose in my 2010 V70R Design ?

I noticed that the hose (coolant overflow hose P/N 31368200) that runs to the top left side of the coolant reservoir is kinked. The hose runs along the top of the engine (under the cover). I purchased a new hose, but I can't see how to remove the old one. Any suggestions? Also, how to install the new hose?
