When you turn the key to start your car, what do you expect to happen? The engine should start right up, right? Wrong. In fact, most cars today require at least two ignition coils in order to start. What are these coils and why do they matter? In this article, we will explore the importance of ignition coils and why they are so important in starting your car. We will also provide a breakdown of how many coils are typically found in a car and what that means for your ownership experience.
What is an Ignition Coil?
An ignition coil is a small, thin wire coil located in the sparkplug of an engine. When the plug is fired, the energy in the coil causes a spark that lights the fuel mixture in the cylinders.
How Many Ignition Coils Do Cars Have?
Cars typically have anywhere from one to twelve coils of wire running through them. These coils are responsible for igniting the fuel in the engine. How many coils your car has is determined by its make and model, as well as its engine type.
Why are Ignition Coils Important?
In a car, an ignition coil is responsible for igniting the fuel in the engine. The coil uses a spark plug to create a small spark that sets off the fuel-air mixture in the engine. If your car has a faulty ignition coil, it may not be able to start or run properly. In addition, if your coil is damaged, it could result in a fire.
What to do if Your Car Has a Dead or Broken Coil?
If your car has a dead or broken coil, the best option is to replace the entire ignition assembly. This is typically done by removing the dashboard, steering wheel, and A-pillar (if applicable), then accessing the coil pack through the firewall. Some replacement coils are available as part of an overhaul kit, while others can be purchased separately. Be sure to verify that the replacement coil packs fit your car’s specific model and year before buying.
How to Replace an Ignition Coil on a Car
Your car’s ignition coil is responsible for starting the engine. It converts direct current (DC) from the battery into alternating current (AC), which is then used to spark the pistons and turn the wheels. When the coil fails, your car won’t start. Here’s how to replace an ignition coil on a car:
1. Turn off the engine and remove the key from the ignition.
2. Remove the screws that hold on the cover of the engine bay.
3. Remove the cover of the engine bay.
4. Locate and remove the ignition coil assembly. Be sure to save all of the wiring connections!
5. Wash and dry all parts before reinstalling them in their original location. Replace any worn or damaged parts as needed.
6. Reinstall the cover and screws, and turn on the engine to test it out!
