Parts for your 2019 Ford Focus-Ignition coils

Keeping Your 2019 Ford Focus Ignition Coils in Top Shape

The ignition coils on your 2019 Ford Focus play a crucial role in ensuring your engine runs smoothly. They take power from the battery and convert it into a higher voltage to ignite the fuel in the engine's cylinders. While they're crafted to be durable, like all components, they can experience wear and tear over time. It's essential to have a good understanding of how to maintain or replace them to keep your Focus running in top condition.

Firstly, recognising the signs of a failing ignition coil is vital. A faulty coil can lead to numerous problems:

• Poor fuel economy due to incomplete combustion.
• Increased emissions which can lead to failing an emissions test.
• Loss of power or misfires, which can be particularly noticeable during acceleration.

If you're experiencing any of these symptoms, it might be time to inspect your car's ignition coils. Here's a breakdown of the process and what you should consider:

1. **Consult Your Manual**: Before diving under the bonnet, it's useful to consult the vehicle's manual. This will give you specific instructions on accessing the ignition coils and any particular nuances of your Focus's engine configuration.
2. **Safety First**: Always ensure the car is turned off and has cooled down before you begin. The last thing you'll want is to be handling hot metal components.
3. **Locating the Coils**: The ignition coils on the Ford Focus are typically situated atop the engine, directly connected to the spark plugs. On the Focus, there's usually one coil per cylinder, with each coil seated right above each spark plug.
4. **Removing the Coils**: Disconnect the negative battery cable to prevent any electrical mishaps. Release the clip attaching the coil to the ignition module and gently pull the coil away. It should slide off with minimal resistance, but take care not to yank it forcefully as this could lead to damage.
5. **Inspecting the Coils**: Once removed, check the ignition coils for signs of wear such as cracks or burns. An electrical tester can be handy to verify if the coils are functioning correctly.
6. **Replacement Process**: If the coil needs replacing, make sure you have a suitable replacement part. Attach the new ignition coil, ensuring it fits snugly back onto the spark plug, and reconnect it to the ignition module. Repeat the same for any additional faulty coils.
7. **Reconnect and Test**: Once the replacement is complete, reconnect the battery cable. Start the engine and monitor it to see if it runs smoothly. This will confirm whether the coil replacement was successful.

Caring for your ignition coils isn't just about avoiding immediate engine issues. Regular inspection and maintenance can extend the lifespan of your coils and improve the overall health of your vehicle. It's a preventive measure that can save you from costly repairs in the future. Aim to check your ignition coils as part of your regular maintenance every 20,000 to 30,000 kilometres, or as recommended in your Ford's maintenance schedule.

There are a few additional tips to keep in mind:

• Always maintain your vehicle's spark plugs in conjunction with the ignition coils. They work in tandem, and worn plugs can overwork the coils, leading to quicker deterioration.
• Make sure the connections are clean and free from debris or corrosion. Rusty connectors can hinder performance and lead to coil failure.
• Use quality parts from reputable suppliers. Genuine parts from Ford or OEM parts can assure you of better quality and performance compared to uncertified components.

The 2019 Ford Focus comes equipped with modern ignition systems that are as reliable as they are effective. By approaching maintenance with care and attention, you can ensure that your car remains reliable and efficient for many years to come. A little effort in understanding and maintaining your ignition system can bring you peace of mind and ensure that you'll spend more time enjoying the drive and less time in the garage.
