What happens if my Lincoln Navigator spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What do I do if I see a pool of liquid under my Lincoln Navigator?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

Are hard starts and stops bad for my Lincoln Navigator engine?

You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.

How often should I clean my Lincoln Navigator fuel injectors?

The cleaning schedule for vehicle fuel injectors varies depending on your driving conditions and the type of fuel you use.

Reference your Lincoln owner’s manual for exact guidelines.

Enhance Lincoln Navigator Performance with a Tune-Up

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, particularly if you want to keep your 2018 Lincoln Navigator in tip-top shape. Regular engine tune-ups can optimize your Navigator’s power on the road. Tune-ups give your engine a boost in efficiency, so you can enjoy improved fuel economy and lower emissions. When you get routine engine tune-ups based on Lincoln's recommendations, you can rest assured you’re investing in your Navigator’s long-term engine performance.

Lincoln Navigator Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2018 Lincoln Navigator. The first is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your Navigator. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your Navigator. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your Navigator's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where to Get a Lincoln Navigator Tune-Up

Schedule your next 2018 Navigator engine tune-up service at Firestone Complete Auto Care. Follow Lincoln's recommended maintenance schedule or book an appointment as soon as you notice one of the following: shaking while the engine is idling, poor fuel economy, knocking noises in the engine, or a lit up check engine light on your dashboard.

*Ask a Firestone Complete Auto Care teammate about full terms and conditions for warranties.
