🔧 Ignition Coils - Replacement

Your XC60 uses one ignition coil per spark plug. Replacing weak coils can fix rough idle, misfires, hesitation, and check-engine lights tied to ignition problems. Since this engine has 6 coils, it’s smart to replace only the failed one unless diagnostics point to more than one.

Difficulty Level: Beginner | Estimated Time: 1-2 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 reduces the chance of setting faults.
• Do not pull on the wiring harness. Use the connector tab and the coil body only.
• Keep dirt out of the spark plug tubes. Debris can cause misfires after the repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover

• Use your hands or an 8mm socket if your cover uses fasteners.
• Lift the cover straight up to release the rubber mounts.
• Set it aside safely.

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 post.
• Keep the cable isolated.

Step 3: Unplug the coil connector

• Locate the ignition coil you are replacing.
• Press the connector lock and gently pull the plug off the coil.
• If the connector is tight, use a trim removal tool to help release the tab without breaking it.

Step 4: Remove the ignition coil

• Use your hand to pull the coil straight up.
• If it sticks, twist it slightly while lifting.
• Do not pry on the valve cover.

Step 5: Inspect the spark plug well

• Look down the tube for oil, water, or broken rubber.
• If you see oil in the tube, the valve cover or plug tube seal may need repair.
• Use a clean cloth to remove loose debris only.

Step 6: Install the new ignition coil

• Apply a small amount of dielectric grease inside the coil boot.
• Push the new coil straight down until it seats fully on the spark plug.
• Reinstall any coil hold-down fastener if equipped and Torque to 8 Nm (71 in-lbs).

Step 7: Reconnect the coil wiring

• Push the connector on until it clicks.
• Lightly tug it to confirm it is locked.

Step 8: Reassemble and reconnect battery

• Reinstall the engine cover.
• Reconnect the negative battery cable with a 10mm socket and tighten it snugly.
• Make sure nothing is left loose in the engine bay.
