ID: 185208
Description: Changing spark plugs is a small but essential...
Steps:
- Open the driver's side door. On the bottom left of the steering column, there will be a small hood release latch.
- Place two fingers under the lip of the release, and pull upwards to release the hood.
- An audible click will be heard.
- Go to the front of your vehicle and locate the hood latch under the hood and off right from the center.
- Push up on the latch to unlock the hood.
- Raise the hood prop.
- Insert the prop rod into the hole.
- Locate the negative battery terminal (negative is black, while positive is red).
- Use a socket to loosen the bolt on the negative terminal clamp.
- Remove the negative terminal clamp from the battery.
- Move the clamp aside so it does not touch the battery terminal or any other metal in the vehicle.
- Use a 10mm socket to remove the two 10mm nuts near the center of the cover.
- Pull up the cover and set it aside with the 10mm nuts.
- Use a 10 mm socket to loosen the bolt on all four ignition coils.
- Press the tabs on the connectors to disconnect them from each coil.
- Remove the ignition coil.
- Place the spark plug socket onto the spark plug.
- Turn the ratchet counterclockwise to loosen the spark plug.
- Take out the spark plug. Repeat for all four spark plugs.
- Lower the new spark plug into the hole. Turn the extension clockwise by hand first until it becomes tight.
- Attach the ratchet and tighten the spark plug a little more. Repeat for each cylinder.
- Reinstall each ignition coil by pressing down to seat the coils correctly.
- Reinstall the four 10mm bolts. Tighten by hand, then use the ratchet for an extra 1/4 turn.
- Reattach the connectors to each ignition coil. Listen for a subtle click. Confirm the electrical connector is secure.
- Repeat for all four ignition coils.
- Align the holes with the studs and oil fill port.
- Place two 10mm nuts.
- Tighten by hand, then 1/4 turn with ratchet.
- Relocate the negative battery terminal.
- Place the terminal clamp over the battery post.
- Tighten the bolt with the ratchet until it is snug.
- Make sure the cable does not move.
- A loose battery terminal can cause a vehicle to not start, so it's best to ensure terminals are tight.
- Lift the hood. Put the hood prop back into its downward position.
- Secure the prop in the plastic holder. Remove all tools and old parts from the engine bay.
- Lower the hood. Press down on the hood to lock it.
- Check to make sure there is no gap between the hood and grill. Repeat pressing down until the hood is locked and cannot be lifted.
