When should Lincoln Navigator spark plugs be replaced?

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 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.

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.

Tune Into Your Lincoln Navigator

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you want your 2004 Lincoln Navigator’s engine to last for a long time. Regular engine tune-ups can optimize your Navigator’s power on the road. 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. 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. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your Navigator can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
