When should Mercury Grand Marquis 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 Mercury’s recommendations.

What should I do if I see leaks under my Grand Marquis?

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.

What do hard starts and stops do to my Grand Marquis engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

Enhance Mercury Grand Marquis Performance with a Tune-Up

Is it tune-up time? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you drive a 1992 Mercury Grand Marquis. Periodic tune-ups can bring more power back to your Grand Marquis’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 follow the guidelines specified by Mercury for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your Grand Marquis’s engine running smoother, longer.

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. The first 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 Grand Marquis. 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. The result? Restored fuel system 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. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
