Jeep Commander Spark Plugs
Jeep Commander Spark Plugs: All You Need to Know
What They Do for the SUV
They combust the mix of air and fuel in its engine, to produce the power the engine runs on. In short, they help start the vehicle.
How They Work
The process, called spark ignition, starts when you turn your key in the ignition lock cylinder, activating the ignition switch. Your battery, a starter motor, a starter solenoid, and an ignition coil then generate an electrical charge. The "spark" travels to the plugs' leads, which capture it; combustion occurs, the engine's pistons pump, its crankshaft turns, and your vehicle's many systems start running.
The Symptoms They're Failing or Bad
Sadly, no spark plug is permanent. For instance, their leads can corrode, that is, if they don't widen too far to conduct electricity properly. Worse yet, they can weaken physically, and if they do, they can break. This almost always results in severe and expensive damage to engine cylinders.
Think your spark plugs have problems? There are signs that'll tell you, and luckily, they usually show up before things get worse. They include:
- Hard startups
- A misfiring engine
- Trouble speeding up
- Rougher idling than normal
- A marked drop in fuel efficiency
If you see any such symptoms, do an engine inspection. Replace any spark plugs necessary according to its results. Otherwise, be sure to change them before they reach the mileage limits recommended in your owner's manual.
