Engine overheating, engine misfiring and stalling, difficulty starting the vehicle, and a check engine light illuminating are some of the most common symptoms of an overheating ignition coil.
You Are Watching: 5 Overheating Ignition Coil Symptoms Updated 04/2024
If you see a component on your automobile overheating, whether it’s the engine or the ignition coil, you need to take action quickly to prevent more damage. It is possible that your car’s engine or ignition coil is overheating all the time for a variety of reasons.
Overheating can be caused by a variety of factors, the most common of which is infrequent maintenance (which can help find malfunctioning components earlier). When your spark plugs are defective or have a large gap, an ignition coil will overheat.
Unfortunately, ignition coils are often overlooked by drivers, despite the fact that even minor damage to this part can result in a disastrous engine failure. Overheating of the ignition coil can cause significant damage, therefore it’s critical that you recognize the warning symptoms early on.
Overheating Ignition Coil Symptoms
In fact, these symptoms aren’t always indicative of a bad ignition coil; they can appear when other parts of the car aren’t working properly.
This is why it is important to conduct a thorough investigation if any of these symptoms or indicators are present.
1. Engine Overheating
No, that should be evident. Your car’s engine may also overheat if your ignition coil becomes too hot.
Engine overheating and other problems can occur if an ignition coil begins to fail and overheat, preventing it from passing enough spark and charge to the engine.

There are several probable causes of engine overheating, but one of them is a faulty overheating coil.
2. Check Engine Light Illuminates
In addition to this, you should be aware of other typical overheated ignition coil symptoms.
It is possible that a damaged ignition coil could affect your engine’s performance, causing the check engine light to come on in your vehicle’s central computer.
The only time your car’s check engine light comes on is when there is a problem with the engine.
As a result, if you see this light on your dashboard, you should inspect your ignition coil. It’s safe to assume that if your check engine light is on, it’s because your ignition coils are scorching.
Check the engine (as a whole) to make sure it’s in good working order as well.
3. Stalling and Misfiring
If your engine sputters or misfires, it’s a good idea to have it checked out. An overheated coil is a contributing factor in this.
A stalling or misfiring engine could be the result of an overheating coil sending erratic sparks to the spark plugs.
Continuing to allow the stalling to go on will either result in the engine being totally switched off or the halt being abruptly interrupted. If you let one of these things happen, you run the danger of causing serious, expensive damage to your vehicle.
4. Poor Fuel Economy
Your ignition coil may be malfunctioning or overheating if you notice a decrease in your car’s fuel efficiency.
When one of the ignition coils or spark plugs stops working, it has an effect on the other. In order to compensate for the lack of power provided by damaged spark plugs, your engine would use more fuel.
5. Hard Starting
One of the symptoms of a faulty ignition coil is a sluggish start. When an ignition coil is defective, the engine is unable to break down because it lacks sufficient power and electrical charge.
You’d hear your engine attempting to crank up, but to no avail, because of a lack of sparks in the cylinders. This is known as “hard starting.”
What To Do When Your Car Ignition Coil is Overheating?
First and foremost, if you detect any of the symptoms described above, you should immediately cease driving. To determine whether or not your ignition coils are overheating, choose a safe place to park your car and open the bonnet.
Overheating coils should not be used while driving. When the coil gets too hot, the insulator weakens and the coil melts.
It’s a surprise that replacing ignition coils isn’t prohibitively costly. A new ignition coil for your car typically costs $150 to purchase and install. The cost of labor, on the other hand, is dependent on the technician you hire to fix your car.
The aging of ignition coils might also cause them to malfunction. This malfunction could be caused by a weak or worn-out ignition coil if you haven’t upgraded to a replacement.
