How does a ignition coil pack work on a car?
As you already know, each coil pack comes with two towers that fire off a spark to two different cylinders simultaneously. This article will take you by the hand (so to speak) and show you how to test them step by step on the car or mini-van in five easy steps.
How to diagnose a bad ignition coil?
To help you to diagnose this type of Direct Ignition System, the following sub-headings (below) will shed some light on the most common symptoms of a bad ignition coil, some basic working theory, the tools you’ll need, and safety precautions you need to take when working on this type of Direct Ignition System (DIS).
How does an ignition coil affect an engine?
The ignition coils in your engine produce an electrical current that’s carried through your ignition cables (spark plug wires) to the spark plug. That current then flows through the plug to detonate the air and fuel mixture inside the cylinder. A faulty ignition coil can result in a misfire or even the engine failing to run.
How many bolts do you need for ignition coil?
Depending on the size of the ignition coil, it may be held on with anywhere from 1 to 4 bolts on most applications. Locate each bolt securing the coil in place and then use a socket of the appropriate size with a ratchet to loosen and remove the bolts. Set each bolt aside somewhere safe to reuse with the new ignition coil.
Can a faulty ignition coil cause a misfire?
That current then flows through the plug to detonate the air and fuel mixture inside the cylinder. A faulty ignition coil can result in a misfire or even the engine failing to run. Once you’ve identified which coil is causing the issue, you can test the ignition coil to be sure it’s the problem.
What do you call a coil pack ignition coil?
Professionals often use the term coil pack to describe any type of modern ignition coil. But, by definition, a coil pack is a group of ignition coils combined together in a single molded block.
