Maintaining Your 2019 Ford Focus: Tips for Ignition System Care

The 2019 Ford Focus does not utilize ignition leads as part of its ignition system. This is because the vehicle is equipped with a more modern ignition system that includes coil-on-plug technology, which effectively does away with traditional ignition leads. For those unfamiliar, ignition leads are typically cables that transmit the electrical spark from the ignition coils to the spark plugs in older ignition systems. However, this doesn't mean you can overlook the ignition system when it comes to routine maintenance of your 2019 Ford Focus.

Even without ignition leads, maintaining the ignition system is crucial for the optimal performance of your vehicle. Here are some key components and considerations for keeping your ignition system in top shape:

1. Spark Plugs: Check your spark plugs regularly according to your vehicle's service schedule. Worn out or fouled spark plugs can lead to poor fuel efficiency, rough idling, and even difficulties starting your car. It's a good idea to inspect them every 30,000 to 60,000 kilometres depending on the type of spark plug used in your Focus. Platinum and iridium spark plugs tend to last longer than copper ones.
2. Coil-on-Plug System: The coil-on-plug ignition system in your Focus eliminates the need for ignition leads but requires that each coil directly sits atop a spark plug. This setup provides strong and precise ignition spark. Inspecting the coils during routine maintenance helps identify any damage or wear that may affect performance. Look for signs like engine misfires, reduced power, or an illuminated check-engine light, which could indicate faulty coils.

To perform basic ignition system maintenance, gather the right tools, including a spark plug socket, ratchet, extension bar, and torque wrench. Replacement of parts like spark plugs or coils will be easier with these at hand. If you're comfortable working with vehicle engines, follow these steps for a DIY ignition system check-up:

• Step 1: Prepare the Vehicle
  Ensure that the engine is off and cool before starting. Disconnect the negative battery cable to avoid any electrical hazards.
• Step 2: Access Spark Plugs
  In most cases, removing the engine cover will provide you access to the ignition coils and spark plugs. Each coil sits on top of a spark plug, which can be gently lifted off with care not to damage the coil.
• Step 3: Remove and Inspect Spark Plugs
  Using a spark plug socket and an extension bar, unscrew each plug and inspect it. Look for any signs of wear such as a white or ashy coating, soot buildup, or excessive gap between electrodes. These indicate the plug is due for a change.
• Step 4: Install New Spark Plugs
  Set each new spark plug into its respective port. Tighten with a torque wrench to the manufacturer's specified torque settings. This ensures they are secured properly without over-tightening.
• Step 5: Reinstall Coils
  After the plugs are securely in place, refit the ignition coils. Ensure they sit snugly atop each spark plug.
• Step 6: Reconnect the Battery
  Once everything is back in place, reconnect the battery cable and start the engine to ensure it's running smoothly.

Keeping tabs on the performance of your Ford Focus's ignition system will go a long way towards ensuring your vehicle runs smoothly and efficiently. Ignition system maintenance might seem a bit daunting at first, but with the right tools and a bit of patience, you can manage this critical aspect of your car's upkeep easily. If you prefer not to handle this yourself, professional automotive services are always a good option to ensure the job is done with precision. Regular check-ups of the ignition components will help prolong the life of your Focus and keep it performing at its peak.
