Parts for your 2020 Subaru Outback-Ignition coils

Ignition Coils on the 2020 Subaru Outback: What You Need to Know

The 2020 Subaru Outback is a popular choice among Aussies looking for a rugged and reliable crossover with plenty of versatility. When it comes to the engine and ignition system, the ignition coils play a key role in keeping everything running smoothly. Ignition coils are definitely fitted to the 2020 Subaru Outback, so it's worth understanding what they do and how to care for them.

Ignition coils are an essential part of the vehicle's ignition system. Their main job is to take the low voltage from the car's battery and transform it into the high voltage needed to ignite the fuel and air mixture inside the engine's cylinders. This spark is what powers the engine, so without properly working ignition coils, the car wouldn't run properly or might not even start.

Specifically, the 2020 Subaru Outback uses coil-on-plug ignition coils, which means each cylinder has its own coil mounted directly on top of the spark plug. This design improves ignition reliability and efficiency and also makes diagnosing ignition-related issues a bit easier. It's a modern setup you'll find in many vehicles today, including Subaru's boxer engine-powered models.

Over time, ignition coils can wear out or become faulty. This can cause various drivability problems, including:

• Rough idling or misfires
• Poor fuel economy
• Difficulty starting the engine
• Illuminated check engine light
• Loss of power or hesitation on acceleration

Because ignition coils are so crucial for the engine's spark delivery, it's important to keep an eye on them as part of regular maintenance. While they don't require routine replacement like spark plugs, they should be inspected if the vehicle starts showing symptoms of ignition trouble or during scheduled servicing.

When it comes time to replace an ignition coil on the 2020 Subaru Outback, it's best to replace only the faulty units rather than all of them at once, unless more than one is showing wear or damage. Since each coil serves one cylinder, a bad coil will often cause that cylinder to misfire, which can be detected via diagnostic tools or symptom analysis.

Replacing an ignition coil is usually straightforward for qualified mechanics. On this model, you can access the coils easily since they're mounted on top of the spark plugs. It typically involves unplugging the electrical connector, unfastening the coil, swapping it out for a new one, and plugging it back in.

A good quality OEM or quality aftermarket ignition coil is important to ensure the replacement lasts as long as possible and works reliably. Cheap coils can cause ongoing issues and may not offer the same heat resistance or durability as well-made parts, especially given the engine bay conditions.

While the coils themselves are relatively durable, exposure to heat, vibration, and age can cause them to fail. Proper maintenance to avoid other engine issues such as oil or coolant leaks can also help extend the lifespan of the ignition coils. If fluid leaks reach the coils, it can lead to premature failure by damaging insulation or causing electrical shorts.

In terms of servicing intervals, Subaru does not usually specify a fixed replacement time for ignition coils unless there is an issue. However, during routine spark plug changes (usually around 100,000 km or so) it is a good idea to have the coils checked as well. If any signs of cracking, corrosion, or damage are found, it's time for a health check by a trusted mechanic or Subaru service centre.

Overall, the ignition coils in the 2020 Subaru Outback are a vital component keeping the iconic boxer engine firing on all cylinders and delivering the dependable performance drivers expect. Paying attention to coil health and addressing any spark issues early can prevent bigger problems, maintain smooth running, and help the Outback keep going strong on every adventure.
