• Turn the ignition off and remove the key/fob from the vehicle.
• Do not pull on the coil wiring harness hard; the connector tab is fragile.
• No battery disconnect is required for this repair.
• Keep debris out of the spark plug wells.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover

• Grip the engine cover at the corners and pull straight up to release the rubber mounts.
• If it feels stuck, use a trim panel tool gently under an edge. Do not pry hard.
• Lift evenly to avoid cracking it.

Step 2: Disconnect the first coil connector

• Find the electrical connector on top of each ignition coil.
• Use a pick tool or flat-blade screwdriver to release the locking tab if needed.
• Pull the connector straight off the coil.

Step 3: Remove the ignition coil

• Pull the coil straight upward by hand to remove it from the spark plug well.
• If it is stuck, gently twist it while pulling up. Do not yank on the wiring.
• Repeat for the remaining coils one at a time.

Step 4: Install the new ignition coil

• Push the new coil straight down onto the spark plug until it seats fully.
• You should feel it click or bottom out firmly.
• Reconnect the electrical connector until the lock engages.

Step 5: Repeat for all coils

• Replace the remaining coils the same way.
• If you are only replacing one failed coil, it is still smart to inspect the others for cracks or oil contamination.
• Clean plug wells help new coils last longer.

Step 6: Reinstall the engine cover

• Align the cover with the mounting posts.
• Press down evenly until all rubber mounts seat.
