2019 Ford Escape Spark Plug Info

Quick Reference

Why the right plug matters

Choosing the correct spark plug for your 2019 Ford Escape is crucial for optimal engine performance, fuel efficiency, and longevity. Spark plugs are not a "one-size-fits-all" component; various factors like heat range, electrode material, and gap play a significant role.

Heat Range: This refers to a spark plug's ability to dissipate heat from the combustion chamber. A plug that's too "cold" might foul more easily with carbon deposits, while a plug that's too "hot" can lead to pre-ignition or detonation, damaging your engine. The factory-specified heat range ensures the plug operates within an ideal temperature window.

Electrode Metal: The primary materials for spark plug electrodes are copper, platinum, and iridium, each with distinct characteristics:

• Copper: These are the most basic and inexpensive. Copper has excellent conductivity but a softer electrode, leading to faster wear. They typically require more frequent replacement intervals.
• Platinum: Platinum plugs offer better durability and longevity than copper, usually lasting twice as long. They provide a more consistent spark over their lifespan.
• Iridium: Iridium is the hardest and most durable of the three, allowing for a finer electrode wire. This results in a more concentrated and efficient spark, improved fuel economy, and significantly extended replacement intervals – often 60,000 miles or more, as seen in your 2019 Ford Escape.

How to gap a spark plug

The spark plug gap is the distance between the center and ground electrodes. An incorrect gap can lead to misfires, reduced fuel economy, and poor engine performance. While many modern iridium and platinum plugs come pre-gapped, it's always a good practice to verify the gap, especially for the 2019 Ford Escape.

To gap a spark plug, you'll need a wire-type spark plug gapping tool. Avoid using disc-style gapping tools, as they can damage fine-wire electrodes. Gently slide the appropriate wire gauge into the gap. If the gap is too small, use the tool to lightly bend the ground electrode outwards. If the gap is too wide, gently tap the ground electrode on a clean, solid surface to close it slightly. Always be gentle and ensure you only bend the ground electrode, never the center electrode.

Replacement procedure tips for the 2019 Ford Escape

Replacing spark plugs on your 2019 Ford Escape, regardless of the engine, will involve similar steps due to its coil-on-plug (COP) ignition system.

• Coil-on-Plug Removal: Each spark plug has its own ignition coil directly mounted on top of it. You'll need to disconnect the electrical connector from each coil and then unbolt and carefully pull the coil pack straight up to remove it. Be gentle to avoid damaging the coil or its boot.
• Anti-Seize Debate: There's ongoing debate regarding the use of anti-seize compound on spark plug threads. Ford, like many manufacturers, often specifies not to use anti-seize on spark plugs with factory-applied coatings, as it can alter torque readings and potentially lead to over-tightening. If the plug has a dull, metallic finish on the threads, anti-seize is generally recommended. Always consult your spark plug manufacturer's instructions or a service manual.
• Dielectric Grease on Boots: Applying a thin layer of dielectric grease inside the spark plug boot (the part of the coil that connects to the plug) is highly recommended. This helps to seal out moisture, prevents corrosion, and makes future removal easier.
• Torque Specifications: Always use a torque wrench when installing new spark plugs. Over-tightening can damage the plug or cylinder head threads, while under-tightening can lead to combustion gas leaks or the plug loosening. The specified torque for your Escape's engines is 11 lb-ft (15 Nm).

Known issues

Fortunately, the 2019 Ford Escape engines (1.5L EcoBoost, 2.0L EcoBoost, and 2.5L Duratec) do not have widespread, notorious spark plug issues like the earlier Ford 3-valve modular engines that were prone to plug breakage. However, always be diligent during the inspection and replacement process.

Factors that could lead to premature spark plug wear or issues include:

• Tune-Related Issues: Modified engines or those with incorrect tuning can put undue stress on spark plugs.
• Oil Fouling: Excessive oil consumption can lead to oil-fouled plugs, causing misfires. This usually indicates an internal engine issue.
• Coolant Leaks: Coolant entering the combustion chamber can also foul plugs.

Always ensure you use the specified spark plug type and gap to maintain the integrity of your ignition system.
