Will it hurt my Mercedes-Benz E450 to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What does a puddle underneath my Mercedes-Benz E450 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.

What do hard starts and stops do to my E450 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.

How frequently do I need to get my Mercedes-Benz E450 fuel injectors cleaned?

Enhance Mercedes-Benz E450 Performance with a Tune-Up

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, especially if you want your 2021 Mercedes-Benz E450’s engine to last for a long time. Routine engine tune-ups can bring power back to your E450. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by Mercedes-Benz for your vehicle’s tune-up schedule, you invest in your E450's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Mercedes-Benz E450

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz E450 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*. A second service option replaces the air and fuel filter in your E450. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your E450’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 E450 can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where to Get a Tune-Up for Your Mercedes-Benz E450

If you’re looking for 2021 E450 engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Mercedes-Benz, or make a service appointment if you notice any of these symptoms from your engine: shaking while the engine is idling, poor fuel economy, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
