How do I change the spark plugs in my Toyota Sequoia?

The engine in my Toyota Sequoia has been misfiring lately, and I want to replace the spark plugs myself rather than go to a mechanic. I’ve heard the process isn’t too challenging, but how can I change the spark plugs in my Sequoia Limited?

To change the spark plugs in a Toyota Sequoia, you will need:

  • Opening the hood and disconnecting the negative battery terminal
  • Finding where the spark plugs are located using the owner’s manual
  • Cleaning the area of loose debris using a vacuum, compressed air, or cloth
  • Removing the spark plug boots one at a time, labeling the order as you go
  • Removing the spark plugs
To install the new spark plugs, you should:
  • Double check the gaps, even if they are preset.
  • Begin installing the new spark plugs by hand to avoid cross-threading.
  • Tighten the spark plugs using the torque wrench.
  • Reattach the spark plug boots in order.
  • Reconnect the battery and close the hood.
