Will it hurt my Mercedes-Benz ML550 to drive with old spark plugs?

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 should I do if I see leaks under my ML550?

Don't ignore puddles of fluid under your Mercedes-Benz ML550. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

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.

Tune Into Your Mercedes-Benz ML550

Is it time for an engine tune-up? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you drive a 2011 Mercedes-Benz ML550. Routine engine tune-ups can bring power back to your ML550. 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’re taking vital steps toward keeping your ML550’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Mercedes-Benz ML550

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz ML550 engine tune-up services. The first 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*. A second service option replaces the air and fuel filter in your ML550. 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 can improve your fuel system’s performance (and therefore, your engine’s 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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
