Removal

  1. Park the vehicle on level ground and let it cool down. If the engine is still hot, you risk getting burned.
  2. Pull the hood release under the dashboard and open the hood. Secure the hood with the hood support.
  3. Locate the battery in the engine bay and disconnect the negative battery terminal. Disconnect negative battery terminal
  4. Spray penetrating oil to the bolts that you will remove, especially if it is the first time the alternator will be replaced. The bolts tend to get rusted and can be difficult to remove otherwise.
  5. Remove the components blocking your access to the alternator, like the power steering fluid reservoir, the overflow reservoir, and any lines.
  6. Take a photo or draw the serpentine belt routing, so you will not have difficulty installing it back.
  7. Use the 14mm wrench with the pipe as an additional handle so you will not have to exert too much force to push it towards the windshield side to release the tension on the belt so you can slide the serpentine belt out. The tensioner socket may not always be 14mm. Loosen the serpentine belt honda pilot ridgeline odyssey
