When should Mercedes-Benz GL450 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 GL450 mean?

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 some driving habits better for my Mercedes-Benz GL450 engine than others?

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.

Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Enhance Mercedes-Benz GL450 Performance with a Tune-Up

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 2012 Mercedes-Benz GL450. Periodic tune-ups can bring more power back to your GL450’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 GL450’s long-term engine performance.

Mercedes-Benz GL450 Engine Tune-Up Services

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz GL450 engine tune-up services. The standard Firestone Tune-Up is one service option. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. The second service focuses on your GL450'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 GL450. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your GL450's mileage and maintenance history can uniquely impact its tune-up needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
