I use 1/4" sockets, a flex shaft or extension with a universal swivel on the end.
Works fine.
No need to remove oil cooler with this setup.

        If you cannot get a socket  on that nut then the oil cooler is needs

that O-ring, then your into a  bigger job.  It's most likely the elbow hose
that's preventing you from  getting in there with the socket.  Try to push a litter
harder so the  socket will pass by that hose so you won't have to loosen the
big nut on the oil  cooler.
