Is it tune-up time? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you want your 1991 Mercedes-Benz 350SD’s engine to last for a long time. Regular engine tune-ups can optimize your 350SD’s power on the road. Tune-ups give your engine a boost in efficiency, so you can enjoy improved fuel economy and lower emissions. When you get routine engine tune-ups based on Mercedes-Benz's recommendations, you’re taking vital steps toward keeping your 350SD’s engine running smoother, longer.
The Firestone Complete Auto Care location in your community offers several Mercedes-Benz 350SD engine tune-up services. The first is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your 350SD. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your 350SD’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your 350SD's mileage and maintenance history can uniquely impact its tune-up needs. If you’re not sure what services are the best fit for your car, let us help!
