To replace the idler pulley on a 2008 Dodge Avenger with a 2.4L engine, first, disconnect the negative battery terminal for safety. Then, remove the serpentine belt by using a ratchet or a serpentine belt tool to relieve tension on the tensioner pulley. Next, unbolt the idler pulley from its mount using the appropriate socket size, and replace it with the new pulley. Finally, reattach the serpentine belt, ensuring it is properly routed, and reconnect the battery.
