How do i change a serpentine belt for a 2004 Toyoto Corolla?
Memorize or take a picture of the belt going through the pulleys. Then your going to have to rotate the tensioner with a breaker bar, long wrench or ratchet into the hex boss, clockwise to release tension on the belt. Slide the belt off and reroute it through the pully's the same way it was on before Make sure the belt is centered on the pulleys and let the tensioner contact the belt again checking that it is tight.
