Does anyone have a procedure for replacing the expansion valve on a 2003 QX4 or Pathfinder?

Looking at it from the engine bay, I see both lines going in and one big bolt. Is that the only bold holding it to the evaporator?

I can't find any procedure for replacing the expansion valve in the FSM (or even an exploded diagram showing it and the evaporator of them).

Thanks!

Okay, I figured it out.

The expansion valve comes out through the engine bay - one bolt to get the lines off, then an allen wrench to remove it from the evaporator.

There is an exploded diagram of it with torque specs in the "Refrigerant Lines" section of the FSM (page HA-153 or HA-154).
