As a responsible car owner, it’s essential to stay on top of routine maintenance tasks to ensure your vehicle runs smoothly and efficiently. One crucial aspect of car maintenance is changing the spark plugs. Spark plugs are responsible for igniting the fuel-air mixture in your engine, and over time, they can become worn out and affect your car’s performance. If you own a 2017 Nissan Pathfinder, it’s vital to know how to change spark plugs to avoid costly repairs and maintain your vehicle’s overall health.
Why Change Spark Plugs?
Spark plugs are designed to last for a certain period, typically between 30,000 to 100,000 miles, depending on the type and quality of the spark plugs. However, driving conditions, fuel quality, and engine type can affect their lifespan. Worn-out spark plugs can lead to a range of issues, including:
- Reduced engine performance
- Decreased fuel efficiency
- Increased emissions
- Difficulty starting the engine
- Engine misfires
Ignoring spark plug maintenance can result in costly repairs, such as replacing the catalytic converter or even the engine itself. By changing spark plugs regularly, you can prevent these issues and ensure your 2017 Nissan Pathfinder runs smoothly and efficiently.
