Changing the serpentine belt on the 2007 Hyundai Sonata is an integral part of maintaining the engine. If the belt becomes worn or damaged, it can shred or break while you are driving. The serpentine belt is responsible for powering your alternator, power steering pump, water pump and fan, and a failure of the fan would cause your car to overheat, your battery to drain and would cause a loss of steering control. To prevent this, the belt should be checked for cracks and breaks every few weeks.

Instructions

  1. 1

    Locate the spring tensioner pulley in the front centre of the engine compartment. The tensioner pulley looks like the rest of the pulleys except it is attached to a spring-loaded arm.

  2. 2

    Locate the routing diagram for the serpentine belt near the bonnet release latch. If there is no such diagram, draw a diagram to indicate what path the belt takes around the pulleys. Make sure to denote which pulleys it goes over and which it goes under.

  3. 3

    Place the socket wrench on the square peg in the centre of the pulley. Turn the tensioner pulley counterclockwise to release the tension on the belt. Slip the old belt off of the pulleys. Slowly release the tensioner pulley.

  4. 4

    Position the new belt on the pulleys, making sure to follow the diagram. Leave the tensioner pulley for last. If the belt is placed wrong, the pulleys will spin in the wrong directions, causing them to wear and break.

  5. 5

    Turn the socket wrench on the tensioner pulley counterclockwise again and slip the belt on to the tensioner pulley. Slowly move the ratchet clockwise to return tension to the belt.
