If you’ve ever replaced a car battery, you know that old car ignition systems can be a real pain. They’re bulky, they don’t work very well, and they’re often difficult to get to. If you have an older car with an old ignition system, it might not be long before it starts refusing to start. Today we’re going to take a look at how an old car ignition works and how you can replace it without too much trouble.
How an Old Car Ignition Works
An old car ignition works by using a key to turn a crank that spins the flywheel. This spin causes the coils in the ignition system to fire, starting the engine.
Types of Ignitions
There are three types of ignition systems in use in modern cars: spark-ignition, compression-ignition, and direct gasoline injection.
Spark-ignition systems use a spark plug to create an electric current that ignites the fuel mixture in the cylinder. Compression-ignition systems use air/fuel injection to combust the fuel mixture directly. Direct gasoline injection systems squirt pressurized gasoline into the cylinders from a nozzle, creating an explosive force that ignites the fuel.
How to Replace a Car Ignition
There are a few things you will need to do in order to replace your car’s ignition. You will need some automotive parts, a Phillips head screwdriver, and a wrench. First, make sure all the doors and windows are closed securely. Second, disconnect all the electrical connectors that may be plugged into your car’s dashboard. Third, remove the screws on the side of your car that hold on the airbag module. Fourth, remove the panel under the steering wheel that houses your car’s ignition switch. Fifth, remove the old ignition switch by unscrewing it from the mounting bracket and pulling it out of the car. Sixth, install the new ignition switch by screwing it into place and reattaching the panel under the steering wheel. Seventh, reconnect all of your electrical connectors and replace any screws that were removed in step four. Eighth, test your car to see if everything is working properly by turning on all of its lights and getting into gear.
Replacing an Ignition Cable
If your car’s ignition system is near or past its expiration date, it may be time to replace the cable. This cable connects the key switch (or button) to the spark plugs and controls how easily they fire. If your car won’t start, chances are high that the igniter cable is defective. The process of replacing it is fairly straightforward and can be done by yourself if you have basic automotive tools and a few hours to spare.
The first thing you’ll need is a pair of pliers. You’ll also need an 8mm socket wrench, wire cutters, a screwdriver, and some penetrating oil. If your old ignition cable is in good condition, you can simply unscrew the four screws that hold it in place and remove it. Once it’s out, take note of the wires’ colors (red, black, yellow and white).
If your old ignition cable is defective or damaged beyond use, you’ll need to purchase a new one. Many parts stores carry replacement cables in different lengths; make sure to get one that’s long enough for your case (8 feet or more should do it). After measuring the length of the new cable you’ll need to buy, find a similar-sized socket
