Step-by-Step Replacement Process

  1. Prepare the vehicle: Park your car on a flat surface, turn off the engine, and disconnect the battery for safety.
  2. Locate the serpentine belt: Open the hood and find the belt routing diagram, usually found on a sticker near the engine bay.
  3. Release tension: Use a belt tensioner tool or breaker bar to rotate the tensioner pulley and relieve tension on the belt.
