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

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 should I do if I see leaks under my 300D?

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 300D 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.

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, especially if you want your 1992 Mercedes-Benz 300D’s engine to last for a long time.

Routine Engine Tune-Up Service for Your Mercedes-Benz 300D

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz 300D engine tune-up services. The first 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*. The second service focuses on your 300D's filters, specifically replacing the air filter and fuel 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 300D’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 300D can determine what kind of service it needs. If you’re not sure what services are the best fit for your car, let us help! Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
