When should Mercedes-Benz R350 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 Mercedes-Benz’s recommendations.

What does a puddle underneath my Mercedes-Benz R350 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.

What do hard starts and stops do to my R350 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.

Tune-Ups to Help Your Mercedes-Benz R350 Run Better

Is your engine overdue for a 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 2009 Mercedes-Benz R350’s engine to last for a long time. Periodic tune-ups can bring more power back to your R350’s engine. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by Mercedes-Benz for your vehicle’s tune-up schedule, you can rest assured you’re investing in your R350’s long-term engine performance.

Engine Tune-Up for Mercedes-Benz R350

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz R350 engine tune-up services. The standard Firestone Tune-Up is one service option. 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 R350. 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 R350's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your R350: 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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
