When should Mercedes-Benz E450 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 E450 mean?

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.

What do hard starts and stops do to my E450 engine?

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.

Enhance Mercedes-Benz E450 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 want your 2024 Mercedes-Benz E450’s engine to last for a long time. Periodic tune-ups can bring more power back to your E450’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 take your car for regular engine tune-ups as recommended by Mercedes-Benz, you can rest assured you’re investing in your E450’s long-term engine performance.

Engine Tune-Up for Mercedes-Benz E450

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz E450 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*. Another service option pays special attention to the filters in your E450. 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 E450’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system 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 Should I Go for My Mercedes-Benz E450 Tune-Up?

Schedule your next 2024 E450 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, engine knocking, or an illuminated check engine light.
