What happens if my Mercedes-Benz SL500 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 do I do if I see a pool of liquid under my Mercedes-Benz SL500?

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 SL500 engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

How frequently do the fuel injectors in my Mercedes-Benz SL500 need to be cleaned?

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Tune-Ups to Help Your Mercedes-Benz SL500 Run Better

Is your engine overdue for a 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 1994 Mercedes-Benz SL500’s engine to last for a long time. Periodic tune-ups can bring more power back to your SL500’s engine. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy.

Mercedes-Benz SL500 Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz SL500 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*. The second service focuses on your SL500'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 SL500. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your SL500: 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! Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
