🔧 Escape - Ignition Coil Replacement

This is a straightforward beginner repair. Your Escape uses four coil-on-plug ignition coils, with one coil sitting directly over each spark plug. Replace the failed coil, or replace all four if they’re similarly aged and you want a matched set.

Difficulty Level: Beginner | Estimated Time: 20-45 minutes

⚠️ Safety & Precautions

• ⚠️ Let the engine cool completely before touching the coils.
• ⚠️ Keep dirt out of the spark-plug wells. Debris can fall into the engine if the plugs are later removed.
• ⚠️ Switch the ignition off and keep the key away from the vehicle.
• ⚠️ Never start or crank the engine with a coil removed.
• ⚠️ Battery disconnection isn’t normally required for this repair.

🔩 Required Parts

HowToo sells all the parts you need for this repair, and the matching ignition-coil aisle is open in the parts sidebar:

• Ignition coil - Qty: 1 for a confirmed failed coil
• Ignition coil set - Qty: 1 if replacing all four
• Dielectric grease - Qty: 1 small tube
• Ignition coil connector - Qty: As needed only if a connector is damaged

Don’t replace all four automatically for one misfire unless testing supports it. Coils aren’t bananas. They don’t have to leave in the same bunch.

📋 Before You Begin

• 📋 Park your Escape on level ground, select Park, and apply the parking brake.
• 📋 Allow the engine to become completely cool.
• 📋 If replacing only one coil, identify its cylinder before disconnecting anything.
• 📋 Take a clear photo of the connectors and wire routing for reference.
• 📋 No infotainment service mode, scan-tool command, or battery registration is required.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Engine Compartment

• Raise the hood and support it securely.
• Put on the safety glasses and nitrile mechanic gloves.
• Locate the four ignition coils in a straight row on top of the engine.

Step 2: Remove the Engine Cover if Equipped

• Use the plastic trim removal tool only if needed to release any wiring retainers obstructing the cover.
• Grip the engine cover near its mounting points and pull it straight upward from the rubber grommets.
• Don’t force the cover sideways because its mounting points can crack.

Step 3: Clean Around the Coils

• Use the soft nylon cleaning brush to loosen dirt around each coil.
• Use the compressed-air nozzle to blow debris away from the coil openings.
• Keep your face away from the debris and wear safety glasses.

Step 4: Disconnect the Electrical Connector

• Press the locking tab on the selected coil connector with your fingers.
• Pull on the connector housing, not the wires.
• If it’s stuck, gently work the housing while holding the release tab. Don’t pry hard against the plastic.

Step 5: Remove the Coil Retaining Bolt

• Fit the 8mm socket and 3-inch socket extension to the 1/4-inch-drive ratchet.
• Turn the retaining bolt counterclockwise and remove it.
• Place the bolt somewhere clean so it can’t fall into the engine compartment.

Step 6: Remove the Old Ignition Coil

• Grip the body of the coil and gently twist it back and forth.
• Pull the coil straight upward once its rubber boot releases from the spark plug.
• Don’t pull the coil by its connector or wiring.
• A slight twist breaks the boot seal.

Step 7: Inspect the Coil and Spark-Plug Well

• Check the old coil boot for cracks, burns, carbon tracking, or torn rubber.
• Carbon tracking looks like a thin black lightning-shaped line along the boot.
• Look inside the spark-plug well for engine oil, coolant, water, or corrosion.
• If liquid is present, stop and correct the leak before installing the new coil.

Step 8: Prepare the Replacement Coil

• Confirm the new and old coils have matching connector positions, mounting points, and boot lengths.
• Apply a very small film of dielectric grease inside the opening at the bottom of the rubber boot.
• Dielectric grease is an insulating silicone grease that helps seal moisture out of the boot.
• Don’t place grease on the electrical connector pins or coat the spark plug heavily.

Step 9: Install the New Coil

• Lower the coil straight into the spark-plug well.
• Push firmly until the boot seats over the spark plug.
• Align the retaining-bolt hole without twisting the coil against the wiring.

Step 10: Install and Torque the Retaining Bolt

• Start the bolt by hand for several turns to prevent cross-threading.
• Use the 8mm socket and inch-pound torque wrench to tighten the bolt.
• Torque to 8 Nm (71 lb-in). Ford service information lists this light torque for the coil-on-plug retainer. charm.li)
• Don’t convert this to 71 ft-lbs. That would break the bolt or damage the valve cover.

Step 11: Reconnect the Coil

• Push the electrical connector straight onto the new coil.
• Continue until the locking tab clicks into place.
• Gently tug the housing to confirm it’s locked.
• Repeat Steps 4 through 11 if replacing the remaining coils.

Step 12: Reinstall the Engine Cover

• Align the cover with its rubber mounting grommets.
• Press straight downward over each mounting point using your hands.
• Use the plastic trim removal tool to reinstall any wiring retainers removed earlier.

✅ After Repair

• ✅ Check that every serviced electrical connector is fully locked.
• ✅ Remove all tools and loose hardware from the engine compartment.
• ✅ Start the engine and let it idle for two to three minutes.
• ✅ Confirm that the engine runs smoothly without shaking, popping, or a flashing check-engine light.
• ✅ Use a compatible scan tool to clear stored misfire codes if available.
• ✅ Take a short test drive, then recheck for warning lights or rough running.
• ✅ If the misfire remains, inspect the spark plug and connector before replacing additional coils.
• ✅ Stop driving if the check-engine light flashes. A continuing misfire can overheat the catalytic converter.
