When should Mercedes-Benz S400 spark plugs be replaced?

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 does a puddle underneath my Mercedes-Benz S400 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 some driving habits better for my Mercedes-Benz S400 engine than others?

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.

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you want your 2010 Mercedes-Benz S400’s engine to last for a long time. Routine engine tune-ups can bring power back to your S400. 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 Mercedes-Benz's recommendations, you invest in your S400's long-term health and engine performance.

Engine Tune-Up for Mercedes-Benz S400

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz S400 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*. Another service option pays special attention to the filters in your S400. Specifically, we replace the fuel filter and air filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your S400’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your S400'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.

Where Should I Go for My Mercedes-Benz S400 Tune-Up?
