Need to clean it. Removed the two bolts that are 10mm, now there is a nut type thing that needs to come off. It is impossible to use a wrench.

Look at the illustration below

Basically I need to get a crows foot I believe its called down there, because a wrench is to big.

I'm going to go buy one but dont know the size, does anyone know for sure what the size is?
Its a Zetec by the way.

thanks
