Are you looking to learn more about ignition coils? Or do you have a bad ignition coil, and you’re not sure what to do? Whatever your reason, you came to the right place. This buyer’s guide has all the information you need about Ford ignition coils.
What Is An Ignition Coil?
We can’t start until we talk about what an ignition coil is, and why it’s important. Car batteries can produce about 12 volts. Spark plugs need many more volts than that. To be more specific, 12K-45K volts. So it’s impossible for spark plugs to draw the right voltage directly from the battery. The solution? Ignition coils.
Ignition coils are small tube-shaped parts. They convert low voltage from the battery into high voltage current. They give the spark plugs enough voltage to keep the engine running. This post has a thorough explanation of what ignition coils are and how they work.
How To Diagnose A Failing Ignition Coil
Under normal circumstances, ignition coils start to go bad around the 100K mile mark. But sometimes they can fail early. When an ignition coil fails in your engine, it’s a pretty big deal. Your engine will no longer run well. So if you think that your Ford may have a bad ignition coil, look no further than this diagnostic guide.
Diagnosing a bad ignition coil involves checking the resistance of the primary and secondary windings. You would need a digital ohmmeter to get the job done.
How To Replace A Ford Ignition Coil
This tutorial outlines the proper way to replace an ignition coil in a Ford engine. The replacement process involves:
- Disconnecting the battery
- Removing the ignition coil(s) from the cylinder(s)
- Installing the new ignition coil(s)
Replacing the ignition coil is a very straightforward process. You only need a flathead screwdriver and a socket wrench. You’ll save a lot of money by replacing your ignition coils at home.
OEM Vs. Aftermarket Ford Ignition Coils
When it’s time to replace your ignition coils, always get OEM replacement coils. It’s because:
- Ford builds OEM ignition coils with quality materials
- Many aftermarket manufacturers build their ignition coils with cheap materials that don’t last long
- Ford builds OEM ignition coils to exact specifications for voltage and size
- Many aftermarket ignition coils have a universal design
This comparison guide goes into more detail about why OEM ignition coils are a much better investment than aftermarket coils.
