Will it hurt my Lincoln Navigator to drive with old spark plugs?

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 should I do if I see leaks under my 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.

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.

How often should I clean my Lincoln Navigator fuel injectors?

The frequency at which car fuel injectors should be cleaned can vary depending on several factors, including the type of fuel used and the driving conditions. Some manufacturers generally recommend a fuel system cleaning as part of your general car maintenance, or as needed based on symptoms of poor fuel system performance.

Tune-Ups to Help Your Lincoln Navigator Run Better

Is your engine overdue for a tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, particularly if you want to keep your 1999 Lincoln Navigator in tip-top shape. Periodic tune-ups can bring more power back to your Navigator’s engine. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. 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.

Lincoln Navigator Engine Tune-Up Services

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*. A second service option replaces the air and fuel filter in your Navigator. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your Navigator's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s 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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where to Get a Lincoln Navigator Tune-Up
