How much does it cost to replace ignition coils on a Subaru?
The cost to replace ignition coils on a Subaru can vary depending on several factors, but on average, it typically ranges from $200 to $400 per vehicle. This includes the cost of the parts and labor required to complete the repair.
Understanding Ignition Coils and Their Importance
Ignition coils are an essential component of a vehicle's ignition system, responsible for providing the high-voltage electrical current needed to ignite the fuel-air mixture in the engine's cylinders. When an ignition coil fails, it can cause a range of issues, including misfiring, reduced engine performance, and decreased fuel efficiency.
Factors Affecting the Cost of Ignition Coil Replacement
- Part Cost: The cost of the ignition coil itself can vary depending on the make and model of the vehicle. Subaru-specific ignition coils typically range from $50 to $150 per coil.
- Labor Cost: The labor cost to replace the ignition coils can range from $100 to $250, depending on the complexity of the repair and the hourly rate of the mechanic.
- Number of Coils: Subaru vehicles typically have one ignition coil per cylinder, so the total cost will depend on the number of cylinders in the engine (usually 4 or 6).
- Accessibility: If the ignition coils are difficult to access, the labor cost may be higher due to the additional time and effort required to complete the repair.
It's important to note that the cost can also be affected by the specific model and year of the Subaru, as well as any additional parts or services that may be required during the repair process.
When to Replace Ignition Coils
Ignition coils typically have a lifespan of around 60,000 to 100,000 miles, but they can fail prematurely due to various factors, such as heat, vibration, and electrical issues. Common signs that it's time to replace the ignition coils on a Subaru include:
- Rough idling or engine misfiring
- Decreased fuel efficiency
- Difficulty starting the engine
- Check engine light illumination
If you notice any of these symptoms, it's best to have your Subaru inspected by a qualified mechanic to determine the root cause and the appropriate course of action.
How do I know if my Subaru coil pack is bad?
If it is faulty, you will experience various performance issues with your Subaru.
- Your Vehicle Struggles to Start.
- Frequent Misfires and Backfires.
- Rough Idling and Vibrations.
- Huge Drop in Mileage.
- Poor Acceleration and Jerking.
- Unusual Engine Sounds.
What is the life expectancy of an ignition coil?
80,000 to 100,000 miles
The ignition coils in your car's engine must consistently generate huge 15,000 to 20,000-volt charges of electricity so the spark plugs can keep igniting the engine's fuel. Despite how hard ignition coils work, they have a relatively long expected lifespan of 80,000 to 100,000 miles.
Are ignition coils worth replacing?
Pros: Preventative Maintenance: If one coil has failed, others may be close to failing as well. Replacing them all can prevent future issues and save on labor costs. Improved Performance: New coils can improve engine performance, fuel efficiency, and reduce misfires, leading to a smoother ride.
How much should it cost to replace ignition coils?
For standard vehicles with conventional ignition coils, replacing a single ignition coil can range from $100 to $300. However, for vehicles equipped with more advanced ignition systems like coil-on-plug (COP) or distributorless ignition system (DIS) coils, the cost may be higher, ranging from $200 to $600 per coil.
What is the life expectancy of a coil pack on a Subaru?
In general, however, ignition coils can last anywhere between 120,000 to 150,000 miles or five to seven years. It's a good idea to check on them before then, so your mechanic can identify any issues before they negatively affect your vehicle.
What are the symptoms of a bad ignition coil?
The signs below from your Lexus dealer will warn you when it's time for repairs to avoid engine damage and expensive repairs.
- The Check Engine Light Is On.
- Your Car Feels Slow.
- Your Car Is Heavy on Gas.
- Your Car's Engine Misfires.
- Your Car Backfires.
- You Struggle with Starting and Stalling Issues.
- You Hear Sputters and Coughs.
How long does it take to replace ignition coils?
Most coil replacement can be done same day, but times do vary between makes and models, so plan on dropping off the car. Think about the last spark plug replacement or “tune-up” done to the car. Changing plugs at the same time as coils may save you some time and money.
Are ignition coils easy to replace yourself?
You can replace a failing ignition coil fairly easily at home, but remember that you're dealing with high voltages so must disconnect your battery before you start.
Can you drive a car with bad coils?
Coil Pack Problems Usually, if a coil pack is bad, there will be a loss of fire or spark in one or more cylinders... Driving with a misfiring cylinder is not safe under any condition. It can cause severe damage to your car's engine and thus most of the people advise not to drive with this problem.
What kills an ignition coil?
Contact failures are generally caused by water intrusion in spark plug recesses and voltage supply problems by a weak or failing battery, or faulty wiring.
