I did this job two summers ago. I posted what I learned here.
Coolant Tank Replacement - Post Replacement Observations
In my case I had no luck pulling the tank into the trunk to disconnect the hoses.
In the engine compartment the tank has rubber hoses that run forward 4-5" and then attach to hard metal lines. Instead of disconnecting the hoses from the tank manifold I disconnected them from the metal lines. They are much easier to reach and you can sort of see what you are doing. See the linked post for more info.
Also get your self a set of the cable actuated clamp pliers. They come in handy.
