When should Mercedes-Benz GL450 spark plugs be replaced?

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 do I do if I see a pool of liquid under my Mercedes-Benz GL450?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are hard starts and stops bad for my Mercedes-Benz GL450 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.

Enhance Mercedes-Benz GL450 Performance with a Tune-Up

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, particularly if you want to keep your 2010 Mercedes-Benz GL450 in tip-top shape. Routine engine tune-ups can bring power back to your GL450. They're designed to help your engine start easier and run more efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you get routine engine tune-ups based on Mercedes-Benz's recommendations, you’re taking vital steps toward keeping your GL450’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Mercedes-Benz GL450

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz GL450 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*. A second service option replaces the air and fuel filter in your GL450. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your GL450's fuel injectors, throttle body, and throttle plate. 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 GL450 can determine what kind of service it 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.
