Parts for your 2016 Ford Fiesta-Ignition coils

Maintaining and Replacing the Ignition Coils on Your 2016 Ford Fiesta

The 2016 Ford Fiesta is equipped with ignition coils, a fundamental component in the vehicle's ignition system. These devices serve the essential function of converting the battery's voltage to a much higher voltage needed to ignite the air-fuel mixture within the engine's cylinders. Proper maintenance and timely replacement of ignition coils ensure smooth engine operation, optimal fuel efficiency, and overall vehicle performance.

Just like any other component in a vehicle, ignition coils can suffer from wear and tear. Here's what you need to know about the signs of worn ignition coils, maintaining them, and the replacement process within the 2016 Ford Fiesta.

• Signs of Failing Ignition Coils
  • Engine Misfire: A failing ignition coil can lead to an engine misfire. You may notice a jerking sensation or a shaking engine while idling.
  • Poor Fuel Economy: A drop in fuel efficiency might be a sign that the ignition coils are not generating a strong enough spark.
  • Difficulty Starting the Engine: If the vehicle struggles to start or takes longer than usual, it could indicate coil issues.
  • Check Engine Light: The Check Engine light may illuminate due to a fault code indicating ignition coil problems.

If you encounter any of these issues, it's advisable to have the ignition system checked by a professional. Continuing to drive with failing ignition coils can damage other engine components, which might lead to more expensive repairs down the road.

• Maintaining Your Ignition Coils
  • Regular Inspection: During routine maintenance, ask your mechanic to inspect the ignition coils for any visible damage or wear.
  • Use High-Quality Fuel: Good-quality fuel can help prevent carbon build-up on the ignition coils, which can negatively affect performance.
  • Ensure Proper Plug Gap: The spark plug gap must be set correctly to ensure maximum efficiency of the ignition coils.

As part of your regular servicing, ignition coils should be inspected and potentially replaced even if they don't exhibit critical failure signs. It's generally recommended to replace the ignition coils every 100,000 to 120,000 kilometres as a preventative measure.

• Replacing Ignition Coils in the 2016 Ford Fiesta
  • Tools and Materials Needed:
    1. Socket set
    2. Torque wrench
    3. New ignition coils
    4. Dielectric grease

Before starting, ensure the engine is cool to avoid burns or other injuries. Disconnect the negative battery terminal to prevent any electrical accidents. Follow these steps for replacing ignition coils in your 2016 Ford Fiesta:

1. Remove any engine cover if present to access the ignition coils. This might involve unscrewing plastic clips or bolts.
2. Identify the ignition coils connected to the spark plugs. Carefully disconnect the electrical connector from each coil - make sure to release any clips gently to avoid breakage.
3. Using the socket set, unbolt the coil from its mount on the engine. Keep track of the bolts, as you will need them to secure the new coils.
4. Once unbolted, gently pull each ignition coil out of their respective spark plug wells.
5. Apply a small amount of dielectric grease to the inside of the new ignition coil boots. This helps prevent moisture and ensures a secure connection.
6. Install the new ignition coils. Push them firmly onto the spark plugs and re-bolt them into place using the original bolts.
7. Reconnect the electrical connectors to each ignition coil. Ensure they're secured properly to avoid connection issues.
8. Reattach any previously removed engine covers once all the coils are installed.
9. Reconnect the negative battery terminal and start the engine to verify a smooth idle and proper operation.

Replacing ignition coils can seem daunting, but by following these steps carefully, you can complete the task efficiently and confidently. If you're unfamiliar or uncomfortable with the process, consulting a professional mechanic is always a good option to ensure safe and satisfactory work.
