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?

Don't ignore puddles of fluid under your Mercury Grand Marquis. 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.

What do hard starts and stops do to my Grand Marquis 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.

Tune-Ups to Help Your Mercury Grand Marquis Run Better

Is it time for an engine tune-up? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, particularly if you want to keep your 2009 Mercury Grand Marquis in tip-top shape. Regular engine tune-ups can optimize your Grand Marquis’s power on the road. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Mercury's recommendations, you’re taking vital steps toward keeping your Grand Marquis’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Mercury Grand Marquis

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2009 Mercury Grand Marquis. One option is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. Another service option pays special attention to the filters in your Grand Marquis. Specifically, we replace the fuel filter and air filter. 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 Grand Marquis'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 Grand Marquis'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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
