Understanding Ignition Coils in the 2017 Subaru XV

The 2017 Subaru XV, a popular choice among Aussies for its versatility and reliability, definitely uses ignition coils as part of its engine system. Ignition coils are crucial components in modern vehicles, including the Subaru XV, because they play a key role in starting the engine and keeping it running smoothly. Without ignition coils, the petrol engine simply would not fire up efficiently, if at all.

Ignition coils serve as the electrical transformer that converts the car battery's low voltage into the thousands of volts needed to create a spark at the spark plugs. This spark ignites the air-fuel mixture inside each cylinder, generating the combustion required for the engine to run. The 2017 Subaru XV's boxer engine relies on this process to deliver its characteristic performance and fuel efficiency.

Each cylinder in the Subaru XV's engine typically has its own ignition coil, sometimes integrated with the spark plug in a coil-on-plug setup. This design eliminates the traditional distributor and high tension leads seen in older cars, improving reliability and reducing maintenance. The ignition coil essentially sits directly above each spark plug, ensuring a precise spark delivery.

Because ignition coils are subject to high heat and vibration under the bonnet, they can wear out over time. When an ignition coil starts to fail, it can cause a range of engine performance issues such as misfires, rough idling, difficulty starting, and even reduced fuel efficiency. Drivers might also see the check engine light pop up on their dashboard. On the 2017 Subaru XV, ignoring a failing ignition coil can lead to more serious engine damage, so addressing it sooner rather than later is wise.

Maintaining the ignition coils on the Subaru XV is generally straightforward but important. During regular servicing, mechanics will often perform diagnostic checks that can identify coil problems early. If a coil shows signs of failure, replacing it is the best course of action. Subaru ignition coils are designed to last for a decent number of kilometres, often beyond 100,000 km, but this depends on driving conditions, maintenance history, and climate.

Replacement of ignition coils on the 2017 XV is a relatively simple task for skilled mechanics. The coil packs can be accessed by removing the engine cover, and replacement coils are widely available both from Subaru dealerships and aftermarket suppliers. It's important to use quality coils that meet or exceed Subaru's specifications to ensure optimal performance and engine health.

To keep ignition coils in good shape, it's also sensible to maintain the rest of the ignition system, including spark plugs and wiring. Spark plugs and ignition coils work hand in hand. Old or worn spark plugs can cause the ignition coil to work harder than it should, leading to premature coil failure. Replacing spark plugs around the same time as ignition coils can save money and provide a smoother running engine.

Some 2017 Subaru XV drivers might be curious if they can spot a faulty ignition coil themselves. Symptoms like engine hesitation when accelerating, a noticeable drop in engine power, or the vehicle stalling unexpectedly can all point to coil issues. However, using a diagnostic scan tool is the best way to confirm ignition coil status because it reads trouble codes from the engine control unit (ECU). A professional inspection is recommended if any of these symptoms appear.

Regular servicing plays a key role in preserving ignition coil health. During scheduled servicing, technicians check the entire ignition system and engine performance. Keeping up with Subaru's recommended servicing schedule, especially around the 100,000 km mark, is a practical way to avoid unexpected ignition coil failure. It also ensures that the vehicle continues to run efficiently, keeping running costs down and extending the life of the engine.

In the end, ignition coils are essential components in the 2017 Subaru XV, working silently behind the scenes to ignite the engine and keep it running smoothly. Treating them with a bit of care during routine servicing and paying attention to early warning signs will keep the Subaru XV on the road and performing well for years to come.
