What happens if my Mercedes-Benz S500 spark plugs fail?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What do I do if I see a pool of liquid under my Mercedes-Benz S500?

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 S500 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.

How frequently do I need to get my Mercedes-Benz S500 fuel injectors cleaned?

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. 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-Ups to Help Your Mercedes-Benz S500 Run Better

Is your engine overdue for a tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, particularly if you want to keep your 2003 Mercedes-Benz S500 in tip-top shape. Routine engine tune-ups can bring power back to your S500. 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 take your car for regular engine tune-ups as recommended by Mercedes-Benz, you’re taking vital steps toward keeping your S500’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Mercedes-Benz S500

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz S500 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*. Another service option pays special attention to the filters in your S500. 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 S500's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your S500 can determine what kind of service it needs. If you’re not sure what services are the best fit for your car, let us help! Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
