How To Check Ignition Coil Of Car

When you’re driving your car, one of the most important things you need to check is the ignition coil. This small device helps to start your engine and ensures that your car engages all the gears. If there’s something wrong with the ignition coil, it can cause all sorts of problems with your car. In this blog article, we will show you how to check this part of your car for problems and how to fix them if necessary.

What is an ignition coil?

An ignition coil is a component of your car’s electrical system that helps to start the engine. The coil creates an electric current when it is connected to the car’s battery, and this current powers the car’s spark plugs. If the coil fails, the engine may not start.

How to check an ignition coil?

If you’re having trouble starting your car, it might be time to check the ignition coil. This is a small component located near the spark plugs and it can become dirty over time. Cleaning it will help start your car more easily. Here’s how to do it:

1. Remove the cover of the ignition coil. It should look like a small box with several spark plug connectors on one end and some wires coming out of it.

2. Inspect the coil for any dirt or debris. If there is anything on it, use a vacuum cleaner to remove it. Be careful not to damage the coil while you’re cleaning it.

3. To clean the coil, put some rubbing alcohol on a cotton swab and wipe around all of its surfaces. Make sure to get into all the nooks and crannies. Let the alcohol dry completely before reassembly.

How to replace an ignition coil in a car

If your car won’t start, or if the engine runs rough after you’ve turned the key, your ignition coil may be defective. Replace it with a new one as a first step in fixing the problem. Here’s how:

1 Remove the spark plugs. If you have an electrical socket, disconnect the battery cable at both ends. Otherwise, remove the screws that hold on the cover over the spark plugs. Tip: Disconnecting the battery cable will prevent starting problems caused by shorted out wires in the event of a crash.

2 Pull out the spark plug wires. Apply power to each spark plug wire with a wrench and unscrew it from its connector. Be careful not to strip or break any of these connectors!

3 Inspect each spark plug for burned or fouled insulation (black dust). If any are fouled, replace them all. Clean and reinstall each wire according to its connectors’ instructions. Reconnect everything in reverse order, making sure all connections are tight before replacing the cover.

4 Reinstall the spark plugs and torque their screws to 17 ft-lbs (25 Nm).

Warning signs of an impending coil failure

There are a few warning signs that an impending coil failure is imminent in a car. Many of these warning signs can be difficult to spot, but if you pay attention to them, you may be able to avoid a costly fix.

One sign that an ignition coil is about to fail is a decreased fuel economy. This happens because the car’s computer is not receiving enough power from the coil to start the engine. Another sign that an ignition coil might need to be replaced isif the car will not start after being left sitting for long periods of time (more than 30 minutes). If you notice either of these problems, it’s important to bring your car in for inspection and repairs as soon as possible.
