01Gather the necessary tools and materials

  • Before starting the serpentine belt replacement, ensure you have the following tools and materials:
  • - New serpentine belt
  • - Socket wrench and appropriate sockets
  • - Serpentine belt diagram (if not provided in the car manual)
  • - Pry bar (if necessary)
  • - Safety goggles and gloves

02Locate the serpentine belt routing diagram

  • The serpentine belt routing diagram is typically located on a sticker under the hood of your car. If it's missing or illegible, consult your car manual or check online for the correct routing diagram for your specific make and model.

03Release tension on the old belt

  • Use a socket wrench and appropriate socket to rotate the tensioner pulley in the direction indicated by the routing diagram. This will release tension on the old serpentine belt, allowing you to remove it.

04Remove the old belt

  • Carefully slide the old belt off the pulleys, ensuring you remember the routing path for installation of the new belt. If necessary, use a pry bar to assist in removing the belt from tight spaces.

05Install the new belt

  • Referencing the serpentine belt routing diagram, thread the new belt around the pulleys in the correct order. Make sure the belt is properly seated on each pulley groove to prevent slipping.
  • Use the socket wrench and tensioner pulley to release tension once again and slide the new belt into place.
  • Double-check the routing to ensure the belt is correctly aligned with each pulley.

06Test the new belt

  • Start the car and let it run for a few minutes to ensure the new belt operates smoothly and without any unusual noise or slipping. If there are any issues, shut off the engine and recheck the routing and tension of the belt.
