What happens if my Mercedes-Benz GL350 spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What do I do if I see a pool of liquid under my Mercedes-Benz GL350?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

What do hard starts and stops do to my GL350 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.

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 GL350 Run Better

Is it time for an engine 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, especially if you drive a 2010 Mercedes-Benz GL350. Periodic tune-ups can bring more power back to your GL350’s engine. 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 follow the guidelines specified by Mercedes-Benz for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your GL350’s engine running smoother, longer.

Mercedes-Benz GL350 Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz GL350 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*. The second service focuses on your GL350's filters, specifically replacing the air filter and fuel 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 GL350’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your GL350: 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.

Where Should I Go for My Mercedes-Benz GL350 Tune-Up?

If you’re looking for 2010 GL350 engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Mercedes-Benz, or make a service appointment if you notice any of these symptoms from your engine: shaking while the engine is idling, poor fuel economy, engine knocking, or an illuminated check engine light.
