Spark Plug Replacement: How to Change Spark Plugs in a 2016 Ford Mustang.

Replacing spark plugs is a crucial part of maintaining your 2016 Ford Mustang's engine performance. This guide will walk you through the steps to change your spark plugs, ensuring your vehicle runs smoothly and efficiently.

Why Spark Plug Replacement is Important

Spark plugs ignite the air-fuel mixture in the engine, creating the combustion needed to power your Mustang. Worn or faulty spark plugs can cause:

  • Poor fuel economy
  • Engine misfires
  • Difficulty starting the engine
  • Reduced acceleration

Tools and Materials Needed

  • New spark plugs (check your owner's manual for the correct type)
  • Spark plug socket
  • Ratchet and extension
  • Torque wrench
  • Dielectric grease
  • Spark plug gap tool
  • Anti-seize lubricant
  • Safety gloves and eyewear

Steps to Replace Spark Plugs in a 2016 Ford Mustang

1. Prepare Your Vehicle

  1. Cool Down: Ensure the engine is cool before starting the replacement process to avoid burns.
  2. Disconnect the Battery: For safety, disconnect the negative terminal of the battery.

2. Access the Spark Plugs

  1. Remove Engine Cover: If your Mustang has an engine cover, remove it to access the spark plugs.
  2. Locate Spark Plugs: Identify the location of the spark plugs. The 2016 Ford Mustang typically has a V6 or V8 engine with the spark plugs located on both sides of the engine.

3. Remove the Old Spark Plugs

  1. Remove Ignition Coils: Carefully disconnect the ignition coil connectors and remove the bolts holding the coils in place. Pull the coils out to access the spark plugs.
  2. Clean the Area: Before removing the spark plugs, clean the area around them to prevent debris from entering the combustion chamber.
  3. Remove Spark Plugs: Use a spark plug socket, ratchet, and extension to carefully remove each spark plug. Turn counterclockwise to loosen and remove.

4. Install the New Spark Plugs

  1. Check Spark Plug Gap: Use a spark plug gap tool to ensure the new spark plugs are gapped correctly according to your owner's manual specifications.
  2. Apply Anti-Seize Lubricant: Lightly coat the threads of the new spark plugs with anti-seize lubricant to prevent them from seizing in the cylinder head.
  3. Insert New Spark Plugs: Carefully thread the new spark plugs into the cylinder head by hand to avoid cross-threading. Use a torque wrench to tighten them to the manufacturer's recommended torque specification.
  4. Apply Dielectric Grease: Apply a small amount of dielectric grease to the inside of the ignition coil boots to ensure a good connection.

5. Reassemble and Test

  1. Reinstall Ignition Coils: Place the ignition coils back over the new spark plugs, secure them with bolts, and reconnect the coil connectors.
  2. Reconnect Battery: Reconnect the negative terminal of the battery.
  3. Start Engine: Start the engine to ensure it runs smoothly. Listen for any unusual noises and check for warning lights.

DIY Option

Replacing spark plugs can be a manageable DIY project if you have the right tools and some mechanical knowledge. Regular spark plug maintenance can enhance your Mustang's performance and fuel efficiency.
