Tune-Ups to Help Your Mercury Grand Marquis Run Better

Is your engine overdue for a 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 drive a 2004 Mercury Grand Marquis. Routine engine tune-ups can bring power back to your Grand Marquis. 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 Mercury's recommendations, you can rest assured you’re investing in your Grand Marquis’s long-term engine performance.

Engine Tune-Up for Mercury Grand Marquis

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercury Grand Marquis 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*. Another service option pays special attention to the filters in your Grand Marquis. Specifically, we replace the fuel filter and air 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 Grand Marquis. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your Grand Marquis: 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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

2004 Mercury Grand Marquis Engine Tune-Up Q&A

  • Will it hurt my Mercury Grand Marquis 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 does a puddle underneath my Mercury Grand Marquis mean? Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.
  • Are hard starts and stops bad for my Mercury Grand Marquis 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.
