⚠️ Safety & Precautions

• Turn the engine off and let it cool completely before starting.
• Ignition coils carry high voltage. Do not touch coil connectors with the engine running.
• Disconnect the negative battery cable if you want an extra safety margin while unplugging coils.
• Keep dirt out of the spark plug wells. Debris can cause misfires after reassembly.
• Use gentle force on the coil connectors and boots. Do not yank on the wires.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover

• Use your hands to pull up on the engine cover and lift it off the mounting grommets.
• Set it aside in a safe place.

Step 2: Disconnect the first ignition coil

• Find the ignition coils on top of the engine, one for each cylinder.
• Use a flat trim tool to gently lift the locking tab on the coil connector.
• Press the connector release and pull the plug straight off the coil.

Step 3: Remove the coil hold-down bolt

• Use a 10mm socket, 3/8-inch ratchet, and 3-inch extension to remove the coil bolt.
• Keep the bolt in order so it goes back into the same position.
• Small bolts strip easily.

Step 4: Pull the ignition coil out

• Twist the coil slightly side to side, then pull it straight up out of the spark plug well.
• If it feels stuck, wiggle it gently instead of forcing it.

Step 5: Install the new ignition coil

• Compare the new coil to the old one to make sure it matches.
• Apply a thin film of dielectric grease inside the coil boot.
• Push the new coil straight down onto the spark plug until fully seated.
• Reinstall the hold-down bolt by hand first.
• Use a 10mm socket and torque wrench to tighten the bolt to 12 Nm (9 ft-lbs).

Step 6: Reconnect the coil connector

• Push the electrical connector onto the coil until it clicks.
• Make sure the lock tab is fully engaged.

Step 7: Repeat for the remaining coils

• Repeat Steps 2 through 6 for each remaining coil.
• If one coil failed from age, replacing all four is often the best long-term fix.

Step 8: Reinstall the engine cover

• Align the cover with the mounting points.
• Press down evenly until it snaps into place.
