Upon going back, I'm noticing the original video on this thread seems to have an aftermarket intake. For stock SS engines, you won't need to remove the IAT sensor. Just remove the snorkle which is held on with 2 belt clamps (yes I'm too tired in the video to remember this).
Tools I used:
Craftsman standard sized flat blade screwdriver
1/2 drive ratchet, although a breaker bar makes this much easier
24mm deep impact socket
zip ties and electrical tape
If you use your own methods and the belt is partially on, use the zip ties under the belt with a few rotations and it will pop back on. I did this 3-4 days ago and no belt issues afterwards.
