What happens if my Mercedes-Benz S450 spark plugs fail?

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 Mercedes-Benz’s recommendations.

What does a puddle underneath my Mercedes-Benz S450 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 Mercedes-Benz S450 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 the fuel injectors in my Mercedes-Benz S450 need to be cleaned?

Mercedes-Benz S450 Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz S450 engine tune-up services. The standard Firestone Tune-Up is one service option. 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 S450. 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 S450'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 S450's mileage and maintenance history can uniquely impact its tune-up needs. If you’re not sure what services are the best fit for your car, let us help! Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
