Spark plugs are small but essential components in your engine. Each one generates an electrical spark that ignites the air-fuel mixture inside the combustion chamber, which is what powers your vehicle. Without functioning spark plugs, your engine simply cannot run.
Most Chevrolet vehicles use one spark plug per cylinder. A 4-cylinder engine has four, a V6 has six, and a V8 has eight. These parts fire thousands of times per minute, so even minor wear can have a noticeable impact on how your vehicle performs.
Also, spark plugs need to be replaced from time to time. Keep reading to know the signs that your plugs need to be replaced and where to get expert service in Hibbing, Minn.
How to Tell When Spark Plugs Need to Be Replaced
One of the most common warning signs is when your car is hard to start. If you turn the key and the engine hesitates, cranks longer than usual, or struggles to fire up, worn spark plugs may be the cause. Other symptoms include rough idling, engine misfires, reduced acceleration, and lower fuel efficiency.
You may also notice your engine feels sluggish during normal driving. In some cases, you might see the check engine light come on. If your car is hard to start on a regular basis and other causes have been ruled out, it is worth having the vehicle inspected right away.
How Often Should Spark Plugs Be Replaced?
Replacement intervals vary depending on the type of spark plug your vehicle uses. Copper spark plugs typically need to be replaced every 30,000 miles. Platinum and iridium spark plugs can last between 60,000 and 100,000 miles or more. Always refer to your owner’s manual for the manufacturer-recommended interval specific to your vehicle.
Driving conditions also play a role. Short trips, stop-and-go traffic, and extreme weather can cause spark plugs to wear faster. Drivers who deal with cold winters may find that worn spark plugs make cold-weather starting even more difficult than usual.
What Spark Plug Maintenance Looks Like
Spark plug maintenance is fairly simple, but it does require the right tools and knowledge to do properly. During an inspection, a technician will remove each plug, check for wear or deposits, and measure the electrode gap. Plugs that are fouled with oil or carbon buildup, cracked, or worn down will need to be replaced.
It is also a good idea to inspect the ignition wires and coil packs at the same time, as these components work together with the spark plugs. Catching a problem with any one of them early can prevent more expensive repairs down the road.
