TOOLS: long nosed pliers
Socket set
Rags
Vaseline
Jubilee clip

1st pic
remove cover,battery cover
Disconnect battery remove battery
Remove battery casing top half this is clipped in should now look like this
Do not remove the two bolts until you remove both hoses that are visible
Now remove top hose by sliding clamp back an inch or so (at this point the USA site say just pull off I tried pulling of but
They are on tight ( I got a rag and put it in boiling water let it sit for a minute and wrung it out and placed round hose this
Let the hose expand slightly and they came of quite easily I repeated this for all three hoses) patience is the key

Now you can remove the two bolts that hold the coolant tank on be patient it a bit fiddly don't push to hard it will
Manoeuvre past the battery cover (you can also take this out I chose not to)

2nd pic
You should now be able to see the location of the third hose gently lever forward and you can see where it attaches to the
Radiator. you have some play in it but not much I gripped tank gently pushed forward to gain access to clamp and slid it
back around an inch again put your hot cloth or equivalent on hose I did this 2-3 times the gently eased hose of I used
the pliers at the hose end and gently but firmly manoeuvred the tank from the hose squeaky bum time over tank removed
(Forgot to say you will have coolant in the tank I put toilet roll in to stop it leaking and a rag under tank )
I them put Vaseline on the new tank hose ends put a jubilee clip on bottom hose and Vaseline around outer hose to help
sliding over this is fiddly but doable I used nutted jubilee clip made it easier , replace other hoses in reverse order refill
With preffered coolant ,do usual resets for battery disconnection

Job done , check for leaks
