Will it hurt my Mercedes-Benz ML350 to drive with old spark plugs?

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 do I do if I see a pool of liquid under my Mercedes-Benz ML350?

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 ML350 engine?

You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.

Tune Into Your Mercedes-Benz ML350

Is it time for an engine 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 2004 Mercedes-Benz ML350’s engine to last for a long time. Routine engine tune-ups can bring power back to your ML350. Tune-ups give your engine a boost in efficiency, so you can enjoy improved fuel economy and lower emissions. When you take your car for regular engine tune-ups as recommended by Mercedes-Benz, you can rest assured you’re investing in your ML350’s long-term engine performance.

Engine Tune-Up for Mercedes-Benz ML350

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz ML350 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*. The second service focuses on your ML350's filters, specifically replacing the air filter and fuel 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 ML350. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your ML350 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.
