🔧 Rogue - Spark Plug Replacement

Replacing the spark plugs restores strong ignition, smooth idle, and good fuel economy. On your Rogue, the plugs sit under the ignition coils on top of the engine, so this is a straightforward “remove coil, remove plug, install new plug” job.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours

⚠️ Safety & Precautions

• ⚠️ Work on a fully cool engine to avoid burns and to prevent thread damage in the aluminum cylinder head.
• ⚠️ Keep dirt out of the spark plug holes—debris can fall into the cylinder and cause engine damage.
• ⚠️ Disconnect the negative battery cable if you’re prone to bumping the starter or working near electrical connectors.
• ⚠️ Do not over-tighten spark plugs; stripped threads are expensive to repair.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Let the engine cool completely (at least 1 hour).
• Open the hood and remove any loose items near the engine bay.
• If disconnecting the battery: use a 10mm socket to remove the negative terminal and move it aside so it can’t spring back.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover (if equipped)

• Pull up on the plastic engine cover to release it from its rubber grommets, or remove any fasteners using a 10mm socket.
• Set the cover aside where it won’t get stepped on.

Step 2: Unplug and unbolt the ignition coils

• Locate the four ignition coils on top of the engine (one per cylinder).
• Use a small flathead screwdriver to gently release the connector lock tab, then unplug the coil connector.
• Remove the coil hold-down bolt using a 10mm socket and 3/8" drive ratchet.
• Twist the coil slightly, then pull straight up to remove it. (The coil is the “pencil-shaped” ignition part that sits on the spark plug.)
• Tip: Do one coil at a time.

Step 3: Clean around the spark plug wells

• Use a shop vacuum to remove loose dust around each spark plug tube.
• Use compressed air blow gun to blow out the spark plug well before removing the plug.
• This prevents grit from falling into the cylinder.

Step 4: Remove the old spark plugs

• Install a 5/8" (16mm) spark plug socket onto a 3/8" drive extension and 3/8" drive ratchet.
• Turn counterclockwise to loosen and remove the spark plug.
• If a plug feels extremely tight, stop and work it back-and-forth gently to avoid thread damage.

Step 5: Install the new spark plugs (by hand first)

• Compare the new plugs to the old plugs to confirm matching length and seat style.
• Place the new plug into the 5/8" (16mm) spark plug socket (rubber insert holds it).
• Thread the plug in by hand using only the extension (no ratchet at first) until it seats. This helps prevent cross-threading (starting threads crooked).
• Tighten with a torque wrench (ft-lb range): Torque to 18 Nm (13 ft-lbs).
• Tip: Don’t use anti-seize on plated plugs.

Step 6: Reinstall the ignition coils

• Put a very small smear of dielectric grease inside the end of the coil boot. (Dielectric grease is a silicone grease that helps prevent moisture and makes future removal easier.)
• Push the coil straight down until fully seated on the spark plug.
• Install the coil bolt using a 10mm socket.
• Tighten snugly; if using a torque wrench, Torque to 8 Nm (71 in-lbs).
• Reconnect the electrical connector until it clicks.

Step 7: Reinstall the engine cover and reconnect battery

• Reinstall the engine cover (press into grommets or tighten fasteners) using a 10mm socket if needed.
• If disconnected, reconnect the negative battery terminal using a 10mm socket and tighten securely.

✅ After Repair

• Start the engine and let it idle for 30–60 seconds. It should run smooth with no shaking.
• Listen for misfires (rhythmic shake) and check that all coil connectors are fully clicked in.
• If the check engine light comes on, re-check coil connectors and consider scanning for codes with a scan tool.
• Take a short test drive and confirm normal acceleration.
