What happens if my Mercedes-Benz 300TE spark plugs fail?

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 300TE?

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 some driving habits better for my Mercedes-Benz 300TE engine than others?

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.

How often do Mercedes-Benz 300TE fuel injectors need to be cleaned?

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

When you take your car for regular engine tune-ups as recommended by Mercedes-Benz, you invest in your 300TE's long-term health and engine performance.

Engine Tune-Up for Mercedes-Benz 300TE

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz 300TE engine tune-up services. The first is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your 300TE.

This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your 300TE's mileage and maintenance history can uniquely impact its tune-up needs.
