When should Lincoln Navigator spark plugs be replaced?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What does a puddle underneath my Lincoln Navigator mean?

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.

What do hard starts and stops do to my Navigator engine?

Hard starts and stops put extra wear and tear on engine components. Smooth, gradual starts and stops, on the other hand, are a great way to help your engine run better. They can also help maximize your fuel economy.

Enhance Lincoln Navigator Performance with a Tune-Up

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, especially if you drive a 2021 Lincoln Navigator. Routine engine tune-ups can bring power back to your Navigator. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you get routine engine tune-ups based on Lincoln's recommendations, you’re taking vital steps toward keeping your Navigator’s engine running smoother, longer.

Engine Tune-Up for Lincoln Navigator

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Lincoln Navigator engine tune-up services. One option is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. The second service focuses on your Navigator's filters, specifically replacing the air filter and fuel filter. 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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

Where to Get a Lincoln Navigator Tune-Up

If you’re looking for 2021 Navigator engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Lincoln, or make a service appointment if you notice any of these symptoms from your engine: decreased gas mileage, "rough" idling or stalling when stopped, engine knocking, or an illuminated check engine light.
