how dificult is to change a drivebelt for a 2013 elantra gt hyunday

not that hard, like this video https://www.youtube.com/watch?v=O4aqIiWR9JU

all serpentine are a pain..look for drive guide schematic on your hood or frame..load it on lift tensioner...start car and it should self adjust.. the trick is getting it on..
