Fan clutch nut size (200tdi, not mine)

Hello All,
I have a friend with a 200tdi 110 that we wanted to (re-)install the fan shroud on, its either the fan or the radiator that has to come out, fan seems easier. What's the size needed for a fan clutch wrench? I'm seeing 32MM but a few searches turned up 36mm.
Thanks!

Can't recall which off the top of my head, but it's a mistake to not own the offset fan clutch tool. It's 32mm on one side 36 on the other
