Engine Tune-Up Service for Your 1985 Mercedes-Benz 500SEL

Tune Into Your Mercedes-Benz 500SEL

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, now is the time to work on that habit, particularly if you want to keep your 1985 Mercedes-Benz 500SEL in tip-top shape. Periodic tune-ups can bring more power back to your 500SEL’s engine. 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 take your car for regular engine tune-ups as recommended by Mercedes-Benz, you invest in your 500SEL's long-term health and engine performance.

Engine Tune-Up for Mercedes-Benz 500SEL

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1985 Mercedes-Benz 500SEL. One option is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your 500SEL. 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 500SEL. This can improve your fuel system’s performance (and therefore, your engine’s performance). Here’s something to remember when choosing services: the mileage and service history of your 500SEL can determine what kind of service it 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.

Where to Get a Tune-Up for Your Mercedes-Benz 500SEL

Questions About 1985 Mercedes-Benz 500SEL Engine Tune-Ups

  • When should Mercedes-Benz 500SEL spark plugs be replaced? 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 500SEL? 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.
  • Are hard starts and stops bad for my Mercedes-Benz 500SEL engine? 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.
