🔧 Ignition Coils - Replacement

The ignition coils on your Rogue send high voltage to each spark plug. If one fails, you may get a rough idle, misfire, poor fuel economy, or a check engine light. This job is straightforward and done from the top of the engine.

Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours

⚠️ Safety & Precautions

• Let the engine cool fully before starting. Coils sit on a hot engine.
• Turn the ignition OFF and remove the key/fob from the vehicle.
• Disconnect the negative battery cable before unplugging coils. This helps prevent electrical damage.
• Do not touch the coil boot tip with oily hands. Keep dirt out of the spark plug wells.
• If the engine is misfiring badly, do not drive far. A severe misfire can damage the catalytic converter.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover

• Lift the engine cover straight up by hand.
• If it is snug, gently work it free from the locating grommets.

Step 2: Disconnect the battery

• Use a 10mm socket to loosen the negative battery terminal.
• Move the cable aside so it cannot spring back and touch the terminal.

Step 3: Unplug the ignition coil connectors

• Press the lock tab on each coil connector.
• Pull the connector straight off by hand. Use a flat-blade screwdriver only if the lock is stuck.
• Work one coil at a time so the connectors do not get mixed up.

Step 4: Remove the coil hold-down bolts

• Use a 10mm socket and 1/4-inch ratchet with the 1/4-inch extension to remove each coil bolt.
• Set the bolts aside in order.
• Torque on installation: 7 N·m (62 in-lbs)

Step 5: Remove the ignition coils

• Twist each coil gently to break it loose.
• Pull the coil straight up and out of the spark plug well.
• If one sticks, pull evenly and do not pry hard on the valve cover.

Step 6: Inspect the spark plug wells

• Look for oil, water, or debris in each well.
• If you find oil in the wells, the valve cover gasket may also need replacement.
• Wipe out light dirt with a clean cloth. Do not drop debris into the cylinder.

Step 7: Install the new ignition coils

• Compare each new coil to the old one before installing.
• Push each coil straight down until it seats fully on the spark plug.
• Install the hold-down bolt by hand first, then tighten with a 10mm socket.
• Torque to 7 N·m (62 in-lbs)
• Do not overtighten the small coil bolts.

Step 8: Reconnect the coil connectors

• Push each connector on until it clicks.
• Lightly tug each one to make sure it is locked.

Step 9: Reconnect the battery and reinstall the cover

• Reattach the negative battery cable with a 10mm socket.
• Install the engine cover by pressing it down onto the locating points.

• If the light stays on, clear codes with a scan tool and recheck for misfire codes.
• Take a short test drive and confirm normal acceleration.
• If the engine still runs rough, the spark plugs may also need inspection.
