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. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Lincoln’s recommendations.

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

Don't ignore puddles of fluid under your Lincoln Navigator. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

Are some driving habits better for my Lincoln Navigator engine than others?

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 do Lincoln Navigator fuel injectors need to be cleaned?

Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Tune Into Your Lincoln Navigator

Is it tune-up time? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, especially if you want your 2005 Lincoln Navigator’s engine to last for a long time. Routine engine tune-ups can bring power back to your Navigator. Tune-ups help your engine start smoothly and run efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). 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

The Firestone Complete Auto Care location in your community offers several 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 goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your Navigator: your vehicle’s maintenance record and mileage can determine which service is best. 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.
