Some interesting points -
They "run" the engine for the air test without oil. Interesting.
They show an operator manually installing the brake line ends in the ABS module, I hope at some point they torque those bolts.
The chain link tool is awesome, I want one.
The connecting rod cracker is also an awesome tool, but I don't need one of those.
Lastly, walking beside something and working on it is quite difficult, that must be a tough job. Good video!
