Noah, most YouTube how to videos seem to have lots a talk, and BS before they do anything, and then a poor description of how or any details. If you watch several videos of one procedure you might get some tips.
Most thing, I just forge ahead on my own and figure it out. Trying to find a decent video of what I want to do is usually the hard part so I skip it.
The power steering or water pump on my 911 has never given me one bit of problem.
I had to replace the PS pump twice on the El Camino in the 371,000 miles. It is fairly easy, just messy. I did have to buy a 18mm crowfoot line wrench to get one fitting off.
