🔧 Escape - Spark Plug Replacement

Replacing the spark plugs on your Escape helps restore smooth idle, strong acceleration, and proper fuel economy. The 2.0L turbo engine uses one ignition coil per spark plug, so you’ll remove the coil packs first, then replace the plugs underneath.

Difficulty Level: Beginner | Estimated Time: 1-2 hours

⚠️ Safety & Precautions

• ⚠️ Let the engine cool completely before starting. Spark plugs thread into the cylinder head, which can be damaged if worked on while hot.
• ⚠️ Disconnect the negative battery cable to reduce the chance of accidental electrical shorts.
• ⚠️ Work carefully around ignition coils and wiring connectors. Plastic connectors can become brittle with heat and age.
• ⚠️ Do not over-tighten spark plugs. The cylinder head is aluminum, and damaged threads are expensive to repair.
• ⚠️ Keep dirt and debris out of the spark plug wells. Anything dropped inside can enter the engine.

📋 Before You Begin

• 📋 Park your Escape on level ground and shift the transmission into Park.
• 📋 Set the parking brake and remove the key or keep the key fob away from the vehicle.
• 📋 Open the hood and allow the engine to cool until it is safe to touch.
• 📋 Disconnect the negative battery cable using a 10mm socket. The negative cable is marked with a minus symbol.
• 📋 A spark plug socket is a deep socket with a rubber insert or magnet that grips the spark plug so you can lift it out safely.
• 📋 Dielectric grease is a non-conductive silicone grease used inside the coil boot to help seal out moisture and prevent the boot from sticking.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the Engine Cover

• Use both hands to lift the plastic engine cover straight upward.
• The cover is held by rubber grommets, so no bolts are normally removed for this cover.
• Set the cover aside where it will not be stepped on.
• Pull upward evenly, not at an angle.

Step 2: Locate the Ignition Coils

• Look across the top of the engine for four ignition coils in a row.
• An ignition coil is the small electrical unit that sits directly above each spark plug.
• Use a shop towel to wipe loose dust from the coil area.

Step 3: Clean Around the Spark Plug Wells

• Put on safety glasses.
• Use the compressed air blower nozzle to blow dirt away from the top of each ignition coil and spark plug well.
• Do not skip this step. Dirt can fall into the engine when the spark plug is removed.

Step 4: Disconnect the Ignition Coil Connectors

• Use your fingers to press the release tab on the first ignition coil connector.
• If the connector is stuck, use a flathead screwdriver gently to help lift the locking tab.
• Pull the connector straight back from the coil.
• Repeat this for all four ignition coils.
• Do not pull on the wires.

Step 5: Remove the Ignition Coil Bolts

• Use an 8mm socket, 3/8-inch drive ratchet, and 3/8-inch drive 6-inch extension to remove the retaining bolt from each ignition coil.
• Place the bolts in a small cup or on a clean towel so they do not get lost.

Step 6: Remove the Ignition Coils

• Grip the first ignition coil and twist it slightly left and right to loosen the rubber boot.
• Pull the coil straight upward by hand.
• If it is stuck, use an ignition coil puller to lift it evenly.
• Repeat for all four coils.
• Lay the coils in order from left to right so each one can go back into the same position.
• Keeping coils in order helps diagnosis later.

Step 7: Remove the Old Spark Plugs

• Insert the 5/8-inch spark plug socket, 3/8-inch drive 6-inch extension, and 3/8-inch drive ratchet into the first spark plug well.
• Turn counterclockwise slowly to loosen the spark plug.
• Once loose, continue turning by hand with the extension to reduce the chance of thread damage.
• Lift the old spark plug out using the spark plug socket.
• Repeat for the remaining three spark plugs.

Step 8: Check the New Spark Plugs

• Use a spark plug gap gauge to verify each new plug gap before installation.
• For your Escape, the spark plug gap should be about 0.028 inch.
• Do not forcefully bend the electrode on fine-wire iridium plugs.
• If a plug is badly out of spec, replace it rather than trying to heavily adjust it.
• Most quality plugs come pre-gapped.

Step 9: Install the New Spark Plugs by Hand First

• Place the first new spark plug into the 5/8-inch spark plug socket.
• Lower it carefully into the spark plug well using the 3/8-inch drive 6-inch extension.
• Turn the extension clockwise by hand only for the first several turns.
• If it does not turn smoothly, stop and restart. This prevents cross-threading.
• Repeat for all four spark plugs.

Step 10: Torque the Spark Plugs

• Attach the 3/8-inch drive torque wrench to the 5/8-inch spark plug socket and 3/8-inch drive 6-inch extension.
• Tighten each spark plug carefully.
• Torque to 15 Nm (11 ft-lbs).
• Do not add anti-seize unless the spark plug manufacturer specifically requires it. Many modern plugs already have coated threads.

Step 11: Inspect and Grease the Coil Boots

• Inspect each ignition coil boot for cracks, oil swelling, burns, or tearing.
• Replace the ignition coil boots if they are damaged or loose.
• Apply a small pea-sized amount of dielectric grease inside the end of each coil boot.
• Use a clean shop towel to wipe away excess grease.

Step 12: Reinstall the Ignition Coils

• Push each ignition coil straight down onto its spark plug until it seats fully.
• Use the 8mm socket, 3/8-inch drive ratchet, and 3/8-inch drive 6-inch extension to reinstall the coil retaining bolts.
• Torque to 6 Nm (53 in-lbs).
• Reconnect each ignition coil electrical connector until it clicks.

Step 13: Reinstall the Engine Cover and Battery Cable

• Align the engine cover with its mounting points and press it down firmly by hand.
• Reconnect the negative battery cable using a 10mm socket.
• Torque to 5 Nm (44 in-lbs).

✅ After Repair

• ✅ Start your Escape and let it idle for one to two minutes.
• ✅ The idle should be smooth with no flashing check engine light.
• ✅ Listen for clicking or snapping sounds that could mean a coil connector is loose.
• ✅ Take a short test drive and check for smooth acceleration.
• ✅ If the battery was disconnected, the idle may relearn during the first few minutes of driving.
• ✅ If a check engine light appears, scan for codes before continuing to drive hard.
