What Do Spark Plugs Do?
Spark plugs are crucial components of your vehicle’s engine. They channel an electrical current to create a spark that ignites the fuel-air mixture in the combustion chamber, powering your engine. Without spark plugs, your car cannot operate, making it essential to replace them when they wear out.
Do Diesel Cars Have Spark Plugs?
No, diesel engines operate differently. Unlike petrol engines, which rely on spark plugs, diesel engines use glow plugs to aid ignition through compression. Glow plugs help to pre-heat the combustion chamber to ensure reliable starting in colder conditions.
How Long Do Spark Plugs Last?
Spark plugs typically need replacing every 30,000 to 50,000 miles. However, modern plugs made with iridium or platinum can last much longer. If you’ve recently purchased a second-hand car, it’s a good idea to replace the spark plugs for peace of mind. Spark plugs are affordable and easy to replace, making regular maintenance worthwhile to ensure optimal engine performance.
How to Change Spark Plugs
Changing spark plugs is a straightforward task that many car owners can do themselves. Here’s a simple guide:
- Remove old spark plugs: Use a socket and ratchet to remove the old plugs.
- Check the gap: Use a gap gauge to ensure the new plugs are properly spaced for your vehicle.
- Install new spark plugs: Carefully thread them by hand into the spark plug hole and tighten them with a socket and ratchet.
- Reconnect the spark plug wires: Finally, reconnect the spark plug wires and start the engine to ensure everything is functioning properly.
