HAH, wow that's extensive.
I only removed the acoustic cover (main engine plastic cover), disconnected and moved rear acoustic cover aside, and removed the air intake box.
Leave electronics box there, you can even leave pressure pipe attached at the throttle body.
That's how you save a lot of time. There's no way you'd do all that under an hour otherwise.
I only needed to move the intake manifold away by a few inches to be able to access the 3rd bolt on the coolant flange. You can work around it.
