🔧 Escape - Ignition Coil Replacement

Your Escape uses coil-on-plug ignition coils (one coil per cylinder) mounted on top of the engine. Replacing a bad coil restores smooth idle, power, and prevents misfires that can damage the catalytic converter.

Difficulty Level: Beginner | Estimated Time: 0.5-1.5 hours

• ⚠️ Keep ignition OFF and the key/fob away from the vehicle while unplugging coils.
• ⚠️ Disconnect the negative battery cable to prevent accidental shorts.
• ⚠️ Pull coils straight up—don’t yank on the wiring harness.

📋 Before You Begin

• 🔸 Park on level ground, shift to Park, and set the parking brake.
• 🔸 Open the hood and let the engine cool.
• 🔸 Plan to replace coils one at a time so connectors don’t get mixed up.
• 🔸 A “dielectric grease” is a non-conductive grease that helps seal the rubber boot against moisture.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover

• Use your hands to pull the engine cover straight upward to release it from the rubber grommets.
• Set the cover aside where it won’t get stepped on.

Step 2: Disconnect the negative battery cable

• Use a 10mm socket with a 1/4" drive ratchet to loosen the negative (–) battery terminal clamp.
• Lift the cable off the post and tuck it aside so it can’t spring back.

Step 3: Unplug the ignition coil electrical connector

• At the coil you’re replacing, use a small flat-blade screwdriver to gently lift the connector lock tab (if equipped), then press the release and pull the connector off.
• Pull the connector housing, not the wires.

Step 4: Remove the ignition coil hold-down bolt

• Use an 8mm socket with a 1/4" drive ratchet and a 6" extension to remove the coil bolt.
• Put the bolt somewhere safe—you’ll reuse it.

Step 5: Remove the ignition coil

• Grip the coil body and pull it straight up to remove it from the spark plug well.
• If it’s stuck, twist the coil slightly while pulling upward (do not pry on the valve cover).

Step 6: Install the new ignition coil

• Apply a very thin smear of dielectric grease inside the new coil boot using a clean fingertip (optional but recommended).
• Push the new coil straight down until you feel it fully seat on the spark plug.
• Reinstall the coil bolt using an 8mm socket, then Torque to 62 in-lb (7 Nm) using a torque wrench (inch-pound).

Step 7: Reconnect the electrical connector

• Push the connector on until it clicks/locks into place.
• Gently tug to confirm it’s fully latched.

Step 8: Repeat for any other coils you’re replacing

• Move to the next cylinder and repeat Steps 3–7.
• One coil at a time prevents mix-ups.

Step 9: Reassemble and reconnect battery

• Reconnect the negative battery cable using a 10mm socket.
• Reinstall the engine cover by lining it up and pressing straight down.

✅ After Repair

• ✅ Start the engine and let it idle for 1–2 minutes; it should run smooth with no shaking.
• ✅ If the check engine light was on, it may take a few drive cycles to clear; if it stays on, the next step is scanning for misfire codes.
• ✅ Take a short test drive and recheck for any hesitation under light acceleration.
