Parts for your 2012 Ford Transit-Ignition coils

Replacing and Maintaining Ignition Coils in Your 2012 Ford Transit

The 2012 Ford Transit is a versatile van known for its reliability and durability. Part of keeping this workhorse running smoothly involves regular maintenance, including the ignition coils. Ignition coils play a crucial role in ensuring your engine runs effectively by converting the vehicle's low voltage into the high voltage needed to initiate the spark that ignites the fuel-air mixture in the engine cylinders. Given the importance of this component, it's wise to know how to replace and maintain them.

If you're noticing signs of rough idling, poor fuel economy, or a check engine light, it might be time to inspect those coils. They should typically last around 100,000 kilometres, but various factors like driving conditions and maintenance schedules affect this timeline.

1. Signs Your Ignition Coils Need Attention:
   • Poor fuel efficiency: An engine misfire due to damaged coils can cause your engine to consume more fuel.
   • Difficulty starting: Faulty coils might lead to a weaker spark, resulting in hard starts.
   • Rough idling: If your vehicle idles roughly or stalls, the coils may not be providing sufficient voltage.
2. Steps for Replacing Ignition Coils:
   • Gather Tools: Before starting, ensure you have the necessary tools like a socket set, screwdrivers, and gloves.
   • Locate the Ignition Coils: Open the bonnet and find the coils. They're generally found on top of the engine, attached to the cylinder head.
   • Disconnect the Battery: It's always a good idea to disconnect the negative terminal of the battery to avoid any accidental electrical shorts.
   • Remove the Old Coils: Unplug the electrical connector and remove the bolts securing the ignition coil to the engine. Carefully pull out the coil.
   • Install the New Coils: Insert the new coil into the engine and secure it with bolts. Reconnect the electrical connector.
   • Reconnect the Battery: Once all coils are replaced, reconnect the battery terminal.
   • Test the Engine: Start the vehicle to ensure replacements were successful. Listen for any unusual noises or check engine lights.
3. Maintenance Tips for Ignition Coils:
   • Regular Inspections: Check coils for any signs of wear or damage every time you do a tune-up or every 20,000 kilometres.
   • Keep the Cylinders Clean: Keeping the engine bay clean can prevent contaminants from damaging the ignition coils.
   • Ensure Proper Ventilation: Proper airflow in the engine compartment prevents overheating, which can shorten coil lifespan.
   • Use Quality Replacements: Opt for high-quality or OEM parts when replacing coils to ensure longevity and performance.
4. When to Seek Professional Help:
   • Lack of Tools or Expertise: If you don't have the confidence or tools to replace the coils yourself, it's best to head to a mechanic.
   • Complex Issues: If the engine issue persists after replacing the coils, it might indicate a more complex electrical problem which should be inspected by a professional.

Proper care and vigilance can extend the life of your 2012 Ford Transit's ignition coils significantly, ensuring your van continues to run efficiently. Regular maintenance and attention to the signs of wear can prevent costly repairs down the road. Always keep an eye out for performance issues and don't hesitate to replace faulty coils to maintain optimal performance of your trusty Transit.
