Solution

1. Preparation

Tools Required: Socket set, torque wrench, spark plug socket, extension bar, ratchet.
Parts Required: New spark plugs (ensure to match OEM specifications).
Disconnect the negative battery terminal to ensure safety while working on the electrical components.

2. Remove Engine Cover

Locate the screws or clips securing the engine cover.
Use the appropriate tool to remove the screws or clips.
Carefully lift off the engine cover and set it aside.

3. Access Spark Plugs

Identify the spark plug locations; there are typically six in the 3.5L V6 engine.
If necessary, remove any components obstructing access to the spark plugs, such as the intake manifold or air intake duct.

4. Remove Old Spark Plugs

Using a spark plug socket and ratchet, carefully loosen and remove each spark plug.
Turn counterclockwise to unscrew the spark plugs from the cylinder head.
Inspect each spark plug for wear and carbon deposits.

5. Install New Spark Plugs

Apply a small amount of anti-seize compound to the threads of each new spark plug (if recommended).
Carefully insert the new spark plug into the cylinder head by hand to avoid cross-threading.
Once hand-tight, use a torque wrench to tighten the spark plugs to the manufacturer’s specified torque (typically around 13 lb-ft, but confirm with the manual).

6. Reassemble

Reattach any components that were removed to access the spark plugs.
Replace the engine cover and secure it with screws or clips.
Reconnect the negative battery terminal.
