Tune Into Your Mercedes-Benz 560SEC

Is your engine overdue for a tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, it might be time to change your ways, especially if you drive a 1990 Mercedes-Benz 560SEC. Routine engine tune-ups can bring power back to your 560SEC. They're designed to help your engine start easier and run more efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you follow the guidelines specified by Mercedes-Benz for your vehicle’s tune-up schedule, you invest in your 560SEC's long-term health and engine performance.

Engine Tune-Up for Mercedes-Benz 560SEC

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz 560SEC engine tune-up services. The first is the standard Firestone Tune-Up.

A second service option replaces the air and fuel filter in your 560SEC.

The result? Restored fuel system performance. Consider this when choosing a tune-up service for your 560SEC: your vehicle’s maintenance record and mileage can determine which service is best.

Common Engine Tune-Up Q&A For 1990 Mercedes-Benz 560SECs

  • What happens if my Mercedes-Benz 560SEC 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 560SEC? 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 560SEC 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.
