[HOW TO] Replace Serpentine Belt, AC Belt, Serpentine Idler Pulley - 2021+ 5.3L/6.2L V8's - Yukon, Tahoe, Suburban, Escalade

[fondupot]

Replaced the belts and idler pulley on my 2021 Yukon 5.3L recently. The Serpentine belt was showing signs of fraying at ~63,000 miles. Replaced the AC belt and Idler pulley while I was in there. Belts are a stretch fit type and are not reusable and need to be cut off to be removed.

Hope the video helps someone!

What am I missing? Cannot the a/c belt be coaxed in to position, one guide over while turning the crank or would it damage the belt doing that?
