🔧 Spark Plugs - Replacement

On your Rogue, the spark plugs sit under the ignition coils on top of the engine. This job is straightforward, but it’s important to keep dirt out of the plug wells and to torque the new plugs correctly so you don’t damage the aluminum cylinder head.

Difficulty Level: Beginner | Estimated Time: 1-2 hours

⚠️ Safety & Precautions

• Work on a completely cool engine. Hot aluminum parts can strip easily and can burn you.
• Keep the ignition key away from the vehicle while unplugging coils.
• Do not drop dirt into the spark plug holes.
• Use hand tools first when loosening plugs. Cross-threading can damage the cylinder head.
• Battery disconnect is not required, but it is a good extra safety step if you want maximum protection.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover

• Use your hands to pull up on the plastic engine cover and remove it from the retaining posts.
• Set it aside safely.

Step 2: Disconnect the air intake tube if needed

• If the intake tube blocks access, use a 10mm socket to loosen the clamps.
• Unclip any attached breather hose by hand.
• Lift the tube out of the way.

Step 3: Unplug and remove the ignition coils

• Use a small pick to release the coil connector locks, then unplug each coil.
• Use a 10mm socket to remove the coil hold-down bolt.
• Pull each ignition coil straight up and out.
• Keep the coils in order.

Step 4: Clean the plug wells

• Use compressed air to blow dirt out of each spark plug tube before removing the plug.
• This helps keep debris out of the cylinder.

Step 5: Remove the old spark plugs

• Use a 5/8" spark plug socket, 3" extension, and 3/8" ratchet to loosen each plug counterclockwise.
• Remove each plug carefully and compare it to the new one.
• If a plug feels tight, work it back and forth gently.

Step 6: Install the new spark plugs

• Check that the new plugs are correct and not damaged.
• Thread each plug in by hand first using the 5/8" spark plug socket and extension.
• Once seated by hand, use a torque wrench to tighten to 18 Nm (13 ft-lbs).
• Hand-thread first to avoid cross-threading.

Step 7: Reinstall the ignition coils

• Push each coil straight down onto its spark plug.
• Install the coil bolt with a 10mm socket and tighten to 8 Nm (71 in-lbs).
• Reconnect each electrical connector until it clicks.

Step 8: Reinstall the intake tube and engine cover

• If removed, reinstall the intake tube and tighten the clamps with a 10mm socket.
• Reinstall the engine cover by pressing it down onto the mounting points.

✅ After Repair
