A few 'shop tips' when working in this area:

Taping a piece of cardboard to protect the radiator from errant 'wrench swings' and slipping prybars is cheap insurance when performing this work.
I learned this lesson the hard way...

Also, I decided to cut my 1-piece fan shroud in half for easy removal without having to remove the fan.
I then reattached the 2 halves to each other with wire ties.
This is a huge convenience upgrade, and knuckle-saving measure.

Put some anti-seize on the threads of that tension adjusting mechanism to save yourself aggrevation in the future.
