Do Subarus have coil packs?
Yes, Subaru vehicles do have coil packs. Coil packs are an essential component of the ignition system in Subaru engines, responsible for providing the high-voltage spark that ignites the air-fuel mixture in the engine cylinders.
What Are Coil Packs?
Coil packs, also known as ignition coils, are electronic devices that transform the low-voltage current from the vehicle's battery into the high-voltage spark needed to ignite the fuel in the engine's cylinders. Each cylinder in an engine has its own dedicated coil pack, which is triggered by the engine's computer to fire at the appropriate time.
Coil Packs in Subaru Engines
Subaru engines, like many modern vehicles, use a coil-on-plug (COP) ignition system. In this design, the coil pack is directly mounted on top of the spark plug, eliminating the need for high-voltage spark plug wires. This configuration provides several benefits, including improved ignition timing, reduced electrical interference, and easier maintenance.
Symptoms of Coil Pack Failure in Subarus
If a coil pack fails in a Subaru, the engine may experience the following symptoms:
- Rough idling or misfiring
- Reduced engine power and performance
- Decreased fuel efficiency
- Illumination of the check engine light
In some cases, a failed coil pack can also cause the engine to stall or not start at all.
Replacing Coil Packs in Subarus
Coil packs in Subaru vehicles are generally easy to access and replace. The process typically involves removing the coil pack from the spark plug, disconnecting the electrical connector, and then installing the new coil pack. It's important to use the correct replacement coil pack recommended by Subaru to ensure proper fit and function.
Overall, coil packs are an essential component of Subaru engines, and understanding their role and potential issues can help Subaru owners maintain the performance and reliability of their vehicles.
How much does it cost to replace a coil pack?
Parts can range from about $35 to more than $300 for one ignition coil, according to the vehicle you drive. Labor costs for replacing the part are usually less than $100.
How much to replace a Subaru ignition coil?
It can cost anywhere between $80 and $300 to replace an ignition coil. The exact cost depends on several factors, including: Your Subaru model. Where you get the job done: at a shop by a mechanic or at home by yourself.
How do I know if my car needs a new coil pack?
If your car makes spluttering and coughing sounds, blame a bad ignition coil. The sounds are from a cylinder that's not firing correctly or not at all during the ignition process. If you hear loud banging noises, it's from exploding unused gas in the combustion cylinders.
Do all vehicles have coil packs?
All except diesels and older gasoline engines. Most modern cars have one ignition coil per cylinder. Typically, the coil is installed right over the spark plug. This setup is called coil-on-plug.
What are the symptoms of a failing ignition coil?
8 Signs Your Vehicle Has a Faulty Ignition Coil in Silver Spring,...
- 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.
- Your Car Shakes and Jerks.
What are the signs of a weak coil pack?
7 Signs of a Faulty Ignition Coil
- Blinking Check Engine Light.
- Coughing, Sputtering Engine.
- Repeatedly Stalling Engine.
- Slower Acceleration.
- Dropping Gas Mileage.
- Backfiring From the Tailpipe.
- Your Chevy Dealer Finds a Flaw.
How do I know if my Subaru coil pack is bad?
Find the spark plug wire terminals and then plug your multimeter in two of them. Make sure that both terminals are pointing directly opposite of each other. The reading should be about 12,800 ohms, plus or minus 15%. If the reading is off, then the coil pack is bad and it needs to be replaced.
How do I know if my Subaru engine is misfiring?
Typically, a misfiring engine will cause the car to vibrate or shake, especially at idle. You might also notice a decrease in power, acceleration, and fuel efficiency. In many modern Subarus, the onboard computer will detect a misfire, illuminating the check engine light on your dashboard.
How long do Subaru coil packs last?
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.
