What happens if my Mercedes-Benz ML550 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 should I do if I see leaks under my ML550?

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.

Are hard starts and stops bad for my Mercedes-Benz ML550 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.

Where can I get a Mercedes-Benz ML550 tune-up?

How frequently do I need to get my Mercedes-Benz ML550 fuel injectors cleaned?

The frequency at which car fuel injectors should be cleaned can vary depending on several factors, including the type of fuel used and the driving conditions. Some manufacturers generally recommend a fuel system cleaning as part of your general car maintenance, or as needed based on symptoms of poor fuel system performance.

Enhance Mercedes-Benz ML550 Performance with a Tune-Up

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, particularly if you want to keep your 2012 Mercedes-Benz ML550 in tip-top shape. Periodic tune-ups can bring more power back to your ML550’s engine. Tune-ups give your engine a boost in efficiency, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). 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 ML550’s long-term engine performance.

Engine Tune-Up for Mercedes-Benz ML550

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz ML550 engine tune-up services. One option is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. Another service option pays special attention to the filters in your ML550. Specifically, we replace the fuel filter and air filter. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your ML550. 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 ML550 can determine what kind of service it needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where to Get a Mercedes-Benz ML550 Tune-Up
