Serpentine belt spec and replacement steps

[staminqia]

I want to replace my serpentine belt and I have read all of the posts on belts but it would be nice to have one post that describes the recommended belt spec whether a 80" or 80.2" or 80.5" is the best for the vehicle and also a step by step tutorial on replacement.

I saw one post about using a rope to pull the belt onto to the tensioner but it would be nice to have a little video or pictures.

Any help would be great.

Thanks.
