wd40 wont do s..t,the clue is in the WD . get yourself some plusgas from eurocarparts etc spray it and give it a good soak well before and get yourself 22mm ring spanner and socket .

wd40 wont do it. be careful not to strip the thread by forcing it too much.

if you use a 02 socket you will need a jubilee clip to stop the forked part opening up,
as mentioned undo the plug/loom and use a ring spanner, it wont slip.

If you can get hold of some kerosene and some auto transmission fluid mix them in equal quantities and apply this to the threads works loads better than plusgas in my experience and cost next to nothing.
