Parts for your 2017 Ford Fiesta-Ignition leads

Maintaining and Replacing Ignition Leads on a 2017 Ford Fiesta

The 2017 Ford Fiesta is a popular model, known for its practicality, efficiency, and reliability. One of the key components ensuring that your Fiesta runs smoothly is the ignition system. Among the various parts of the ignition system are the ignition leads, also known as spark plug wires, which are crucial for transferring electrical current from the ignition coil to the spark plugs. If you're wondering whether your 2017 Ford Fiesta uses ignition leads, the answer largely depends on the specific engine configuration.

Many modern vehicles, including some variants of the 2017 Ford Fiesta, are equipped with coil-on-plug systems which do not use traditional ignition leads. However, if your Fiesta does use ignition leads, understanding their maintenance and replacement can help extend the life of your vehicle and ensure optimal performance.

When it comes to maintaining or replacing the ignition leads on your 2017 Ford Fiesta, periodic inspection and servicing are essential. Ignition leads are generally quite durable, but wear and tear over time can cause them to degrade, leading to poor performance, reduced fuel efficiency, and even engine misfires.

1. Signs You May Need to Replace Your Ignition Leads
   • Increased difficulty starting the vehicle
   • Engine misfires or rough idling
   • Poor acceleration
   • Noticeable decrease in fuel efficiency
   • Visible wear or damage to the leads, including cracks or splits in the insulation
2. Steps for Replacing Ignition Leads

   Replacing the ignition leads on your Fiesta is a task you can undertake yourself if you're comfortable with basic vehicle maintenance, however, consulting a professional mechanic is always a good choice if you're uncertain.

   1. Ensure the vehicle is turned off and cooled down. Working with a hot engine can be dangerous.
   2. Open the bonnet and locate the ignition leads. They will be connected to both the ignition coil(s) and the spark plugs.
   3. Carefully remove one lead at a time. It's important to replace each lead individually to prevent mixing up the connections, which could lead to engine running issues.
   4. Check the new leads against the old ones to ensure compatibility. They should be the same length and have similar connectors.
   5. Attach the new ignition lead, ensuring a secure connection at both the coil and spark plug.
   6. Repeat for each lead, following the same one-at-a-time process.
3. Preventive Maintenance Tips

   While replacement is sometimes necessary, preventive maintenance can extend the life of your ignition leads significantly.

   • Regularly inspect the leads for signs of damage. Even if there are no apparent issues with vehicle performance, visible damage means replacement should be considered.
   • Keep the ignition leads clean. Dirt and grime can exacerbate wear on both the leads and their connections.
   • When replacing spark plugs, it's a good idea to inspect the ignition leads and replace them if needed.
4. Benefits of Proper Ignition Lead Maintenance

   Regular checks and timely replacement of ignition leads directly impact your vehicle's performance. With well-maintained leads, you can expect:

   • Smoother and more reliable engine start-ups
   • Improved fuel efficiency and performance
   • Reduced risk of engine misfires and accompanying damage
   • Extended operational lifetime for your vehicle's ignition system and engine
5. Consulting a Professional

   If you're not confident handling vehicle components or if the problem persists even after replacing the ignition leads, it might be time to consult a professional mechanic. They can provide a comprehensive diagnosis and ensure your Fiesta runs as smoothly as possible.

By keeping an eye on the condition of your ignition leads and following a routine maintenance schedule, you'll enhance the performance and longevity of your Ford Fiesta. Whether you're tackling the maintenance yourself or relying on a professional, understanding this aspect of your vehicle's care will keep you driving smoothly for kilometres to come.
