What happens if my Mercedes-Benz E420 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 should I do if I see leaks under my E420?

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 E420 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.

Enhance Mercedes-Benz E420 Performance with a Tune-Up

Is it tune-up time? 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 1997 Mercedes-Benz E420. Routine engine tune-ups can bring power back to your E420. 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 take your car for regular engine tune-ups as recommended by Mercedes-Benz, you can rest assured you’re investing in your E420’s long-term engine performance.

Routine Engine Tune-Up Service for Your Mercedes-Benz E420

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz E420 engine tune-up services. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. Another service option pays special attention to the filters in your E420. Specifically, we replace the fuel filter and air filter. 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 E420’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your E420's mileage and maintenance history can uniquely impact its tune-up 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.

Where Should I Go for My Mercedes-Benz E420 Tune-Up?

Schedule your next 1997 E420 engine tune-up service at Firestone Complete Auto Care. Not sure when you’re due for a tune-up? Use Mercedes-Benz’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: decreased gas mileage, "rough" idling or stalling when stopped, knocking noises in the engine, or a lit up check engine light on your dashboard.
