Parts for your 2017 Nissan Navara-Ignition coils

Ignition Coils on the 2017 Nissan Navara: What They Do and How to Maintain Them

The 2017 Nissan Navara is a solid and reliable ute, loved by many Aussie tradies and weekend warriors alike. Under the bonnet, it features a traditional spark ignition system that relies on ignition coils to get the engine running smoothly. Ignition coils are definitely an important part of this model's engine setup, so understanding what they are and how to care for them is key to keeping your Navara firing on all cylinders.

Ignition coils are essential components in petrol engines like the 2017 Navara's. Their main job is to convert the 12-volt power from the battery into the high voltage needed to create a spark at the spark plugs. This spark ignites the air-fuel mixture inside the engine's cylinders, allowing combustion to occur and the engine to produce power. Basically, without ignition coils, the spark plugs won't fire, and your Navara's engine just won't start or run properly.

The 2017 Nissan Navara's engine management system works closely with the ignition coils to ensure that the spark timing is just right. Modern ignition coils, including those fitted to the Navara, are typically 'coil-on-plug' designs. This means each spark plug has its own ignition coil sitting directly above it, rather than sharing a coil pack with other cylinders. This setup improves ignition reliability and performance by delivering a stronger and more consistent spark.

When it comes to maintenance, ignition coils don't usually require frequent attention like oil changes or air filters. However, over time and with high mileage, ignition coils can wear out or fail. Symptoms of faulty coils can include rough idling, engine misfires, reduced fuel economy, and difficulty starting the engine. If you notice these signs on your 2017 Navara, it might be time to have the ignition coils inspected or replaced.

Replacing ignition coils is straightforward but it's important to use genuine or high-quality aftermarket parts to maintain engine performance. Because each coil is connected directly to a spark plug, it's wise to inspect the spark plugs at the same time and replace them if they're worn. When one coil starts to fail, it's common practice to replace all of them at once to avoid staggered failures down the track.

During servicing, mechanics often perform diagnostic checks on the ignition coils using scan tools that read engine error codes. The onboard computer will indicate which coil might be causing trouble, making pinpointing issues much easier. If any coil is performing poorly, replacing it will often restore smoother combustion, better throttle response, and cleaner emissions.

In terms of lifespan, ignition coils on the 2017 Nissan Navara can typically last over 100,000 kilometres if the engine is well maintained. But any exposure to extreme heat or moisture can reduce their durability. Regular servicing and keeping the engine bay clean can help extend the life of ignition coils.

DIY enthusiasts can change ignition coils themselves as long as they follow safety precautions like disconnecting the battery to avoid electric shocks. The coils are accessed by removing the engine cover and simply unplugging the electrical connector and bolt holding the coil in place. However, if unsure, a professional service is always recommended to avoid any damage or incorrect installation.

All in all, ignition coils are a critical part of the 2017 Nissan Navara's ignition system. Taking care of them through regular maintenance checks and timely replacement can save owners from unnecessary hassles and keep the ute running smoothly for years. Whether you're driving around town or heading out on a tough off-road adventure, reliable ignition coils ensure the engine starts easily and performs efficiently every time.
