When should Mercedes-Benz 300SD spark plugs be replaced?

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

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 300SD 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.

Tune Into Your Mercedes-Benz 300SD

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, especially if you want your 1983 Mercedes-Benz 300SD’s engine to last for a long time.

Engine Tune-Up for Mercedes-Benz 300SD

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz 300SD engine tune-up services. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. The second service focuses on your 300SD's filters, specifically replacing the air filter and fuel filter. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your 300SD. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your 300SD: your vehicle’s maintenance record and mileage can determine which service is best. 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.
