🔧 Rogue - Ignition Coil Replacement

You’ll be removing the engine cover, unplugging each ignition coil, and swapping them out one by one. This restores proper spark to the engine and can fix misfires, rough idle, and hesitation.

Difficulty Level: Beginner | Estimated Time: 1-1.5 hours

⚠️ Safety & Precautions

• ⚠️ Hybrid safety: Do not touch any orange high-voltage cables or connectors; you are only working on the gasoline engine side.
• ⚠️ Allow the engine to cool fully before starting; hot parts can burn you.
• ⚠️ Disconnect the 12V battery negative terminal to prevent accidental cranking or short circuits.
• ⚠️ Keep metal tools away from battery terminals and electrical connectors to avoid sparks.
• ⚠️ Work in a well-ventilated area with the vehicle on level ground and the parking brake set.

📋 Before You Begin

• Park your Rogue on level ground, shift to P (Park), and set the parking brake.
• Turn the ignition fully off and remove the key or key fob from the vehicle.
• Open the hood and support it with the hood prop rod.
• Disconnect the 12V battery negative terminal using a 10mm socket, then move the cable aside so it cannot spring back.
• Let the engine cool until you can comfortably touch metal parts under the hood.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover

• Use your hands to gently pull up on the plastic engine cover; it is usually held by rubber grommets that pop off studs.
• If it feels stuck, use a plastic trim tool to carefully pry near each corner.
• Lift the cover off and set it somewhere clean so dirt doesn’t get on the underside.

Step 2: Locate the ignition coils

• The coils are the four small rectangular units on top of the engine, each with a wiring connector and a bolt, one per cylinder.
• Take a picture with your phone now so you can see how everything looked before you started. Photos save confusion later

Step 3: Disconnect the ignition coil electrical connectors

• On one coil at a time, press the small plastic tab on the connector with your thumb or a flathead screwdriver and pull the connector straight off.
• If the tab is stubborn, use needle-nose pliers gently on the tab, being careful not to break it.
• Repeat for each coil, but keep the wires routed as they are; don’t force or twist them.

Step 4: Remove the ignition coil hold-down bolts

• Place a 10mm socket on your 3/8" ratchet with a 3"-6" extension.
• Remove the single 10mm bolt holding each coil to the valve cover; turn counterclockwise to loosen.
• Keep all bolts in a small tray or magnetic dish so they don’t get lost.

Step 5: Remove the ignition coils

• Grasp the first coil by its body and gently twist it left and right while pulling upward to slide it out of the spark plug tube.
• If it feels stuck, twist a little more; do not pry with metal tools on the plastic body.
• Inspect the coil boot (the rubber tube) for oil or heavy carbon; note any cylinder that looks different for future reference.
• Repeat for the remaining coils, one by one.

Step 6: Prepare the new ignition coils

• Compare each new coil with an old one to confirm the same shape, connector, and length.
• Apply a thin film of dielectric grease inside each new rubber boot opening; this helps sealing and later removal. Use very small amount

Step 7: Install the new ignition coils

• Insert the first new coil straight down into the spark plug tube; make sure it seats fully on the spark plug.
• Push down by hand until you feel it bottom out; it should sit flat against the valve cover.
• Repeat for all four coils.

Step 8: Reinstall and torque the coil bolts

• Start each 10mm bolt by hand into its hole to avoid cross-threading.
• Use the 10mm socket and ratchet to snug each bolt lightly.
• Then use a torque wrench with the 10mm socket and tighten each coil bolt to 8 Nm (71 in-lbs). Do not overtighten; the threads are in aluminum.

Step 9: Reconnect the electrical connectors

• Push each connector straight onto its coil until you hear or feel a solid click.
• If a connector looks dirty or slightly corroded, spray a small amount of electrical contact cleaner on it and let it dry before reconnecting.
• Gently tug each connector to confirm it is locked in place.

Step 10: Reinstall the engine cover

• Check that no tools or rags are left on the engine.
• Align the engine cover’s rubber grommets with the metal studs on the engine.
• Press down firmly at each corner until the cover snaps into place.

Step 11: Reconnect the 12V battery

• Use a 10mm socket to reinstall and tighten the negative battery terminal clamp.
• Tighten to about 5 Nm (44 in-lbs)—snug but not crushing the clamp.
• Make sure the terminal does not twist and is fully seated on the post.

✅ After Repair

• Turn the ignition on and start your Rogue; it may crank slightly longer the first start after battery disconnect, this is normal.
• Listen for a smooth idle—no shaking, misfire pops, or flashing check engine light.
• Take a short test drive: gentle acceleration first, then a few stronger accelerations to confirm the misfire or hesitation is gone.
• If the check engine light was on before, you can clear stored codes with a basic OBD-II scan tool, or they may clear automatically after several drive cycles.
• Recheck under the hood for any loose connectors or parts and ensure the engine cover is secure.
