1989 Mercedes-Benz 300E Engine Tune-Ups & Maintenance

Tune Into Your Mercedes-Benz 300E

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 drive a 1989 Mercedes-Benz 300E. Regular engine tune-ups can optimize your 300E’s power on the road. 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’re taking vital steps toward keeping your 300E’s engine running smoother, longer.

Engine Tune-Up for Mercedes-Benz 300E

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1989 Mercedes-Benz 300E. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. The second service focuses on your 300E'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 300E. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your 300E: your vehicle’s maintenance record and mileage can determine which service is best. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Questions About 1989 Mercedes-Benz 300E Engine Tune-Ups

  • Will it hurt my Mercedes-Benz 300E to drive with old spark plugs? 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 do I do if I see a pool of liquid under my Mercedes-Benz 300E? Don't ignore puddles of fluid under your Mercedes-Benz 300E. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.
  • What do hard starts and stops do to my 300E 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.
