1985 Mercedes-Benz 500SEC Engine Tune-Ups & Maintenance

Tune Into Your Mercedes-Benz 500SEC

Is it tune-up time? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, especially if you want your 1985 Mercedes-Benz 500SEC’s engine to last for a long time. Regular engine tune-ups can optimize your 500SEC’s power on the road. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Mercedes-Benz's recommendations, you can rest assured you’re investing in your 500SEC’s long-term engine performance.

Routine Engine Tune-Up Service for Your Mercedes-Benz 500SEC

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz 500SEC 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*. A second service option replaces the air and fuel filter in your 500SEC. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your 500SEC's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your 500SEC'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. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Common Engine Tune-Up Q&A For 1985 Mercedes-Benz 500SECs

  • Will it hurt my Mercedes-Benz 500SEC to drive with old spark plugs? 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 500SEC 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.
  • Are some driving habits better for my Mercedes-Benz 500SEC engine than others? 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.
