An ignition coil is a crucial part of the ignition system that produces the spark needed to start the engine. However, a number of problems may cause the car to overheat and prevent it from starting. In that instance, maintaining a cool ignition coil can benefit the car.
How to keep ignition coil cool? Ensure proper airflow, keep the compartment clean, apply heat-resistant coating, and regularly inspect to keep the ignition coil cool. However, if you experience signs such as engine misfires or reduced fuel economy, immediately check the coil and fix the problem if needed.
You may prefer professional solutions, but here are a few easy ways to keep the ignition coil cool. Let’s read and explore how to take better care of your ignition coil.
What Causes Ignition Coil to Get Hot?
The ignition coil can get hot for various reasons in your vehicle. Here I have listed the few major issues that may cause Ignition coil to get hot.
- Bad ignition module
- Faulty spark Plug
- Ignition switch Problem
- Loose connection
- Faulty Ignition Coil
- Low engine oil

How to Keep Ignition Coil Cool?
Keeping an ignition coil cool is essential for enjoying the uninterrupted performance of your vehicle. Here are a few ideas that may help keep your ignition coil cool.
Keep Proper Airflow Around the Coil:
The coil, while generating the spark, becomes hot; there is a need for adequate airflow to keep the ignition coil cool. If the airflow is poor, it may cause the ignition coil to overheat and damage the coil.
To ensure correct airflow, ensure the coil is positioned correctly. There should be enough space around the ignition coil to circulate the air freely. To do that, do not place the objects or parts closer to the ignition coil. It may restrict the airflow.
Also, check for the surrounding components, such as spark plug wires or intake manifolds; they should be in the right place. Otherwise, they may also block the airflow.
It is also essential to check the air filter regularly and replace it when essential. A clogged air filter can also restrict airflow and cause your ignition coil to overheat.
Never allow your engine to become hot; ensure the proper engine oil level keeps the engine cool. A hot engine may also cause ignition coil to overheat due to hot surrounding air.

Ensure Engine Compartment Cleanliness:
The debris accumulation around the Engine compartments can restrict the airflow, which may lead to ignition coil overheating.
Dust, dirt, or other debris can easily accumulate around your ignition coil, which needs regular cleaning. Make it your routine to remove such particles to keep the ignition coil in good condition and cool.
Apply Heat-Resistant Coating on the Ignition Coil:
You should also apply a heating-resistant coating around the ignition coil to keep it cool. Also, apply the coating to the surrounding components. It may act as a barrier and prevent heat from trapping or penetrating inside the coil or nearby components.
You can use heat-resistant tape around the ignition coil or its nearby components. There are many options, but I recommend Bertech High-Temperature Kapton Tape for consistent performance.
Regularly Check the Ignition Coil for Overheating Signs:
To prevent ignition coil overheating issues, make it a habit to check it regularly. You should inspect for signs such as cracking, melting, discoloration, or corrosion around the components.
If you see such issues, immediately fix the issue to prevent the ignition coil or surrounding components from being damaged. Doing so can also protect your vehicle from severe damage, such as engine or component problems.

How to Increase Ignition Coil Power?
When it comes to increasing the ignition coil power, you have a few simple ideas. Here is a list of ideas that may help boost ignition coil power.
- The number of wire turns around a coil can increase the coil’s power.
- The next thing is to increase the movement speed of the magnet across the coil wire.
- You can also increase the power by making the best connection between the spark plug and coil wire.
- Reduce the gap between the coil and the flywheel.
- Use a more powerful magnet for the flywheel

Tips for Keeping Ignition Coils Cool
- Install the heat shields or the insulators to prevent the ignition coil from overheating.
- Make sure the coil has enough airflow and that your engine bat is clean at all times.
- To prevent overheating, make sure the spark plug gap is the right amount.
- Always choose good quality ignition coils for satisfactory performance.
- To maintain the cooling system in better condition, replace any damaged surrounding components right away.

Frequently Asked Questions (FAQs):
Can an overheating ignition coil cause other problems in the engine?
Yes, an overheating ignition coil can lead to engine issues. It may result in misfires, reduced fuel efficiency, and even engine stalling. Overheating can cause the coil to malfunction, affecting spark plug performance and overall combustion, leading to engine-related problems. Regular maintenance is essential to prevent such issues.
How often should I have my ignition coil checked?
It depends on different factors; however, if you do not face any issues, you should check the coil at least once a year. But if you face signs such as reduced fuel efficiency, rough idling, or engine misfire, check for an ignition coil. A regular and timely inspection can prevent severe damage.
Should I grease my Ignition Coil?
Greasing the ignition coil is advised by some experts, as it may help keep the coil cool. But it is also essential to use only a tiny amount; avoiding applying too much can interrupt the conductivity. It is better to avoid applying grease to the ignition coil until you have the risk of moisture.
How long do ignition coils last?
No one can tell the exact life span of the ignition coil. Depending on the brand, quality, and problems with your car, it may differ. If there is an engine overheating or maintenance issue, it may last any time. However, if you maintain it well, a coil may last, on average, for 80,000 to 100,000 miles.
Conclusion:
Keeping an ignition coil cool is essential for ensuring the smooth functioning of the ignition system. It can be overheated for many reasons. But if you follow the instructions above, you can prevent it from overheating. Proper care and maintenance prevent the coil and other parts, such as engine and ignition system components, from severe damage.
