What happens if my Mercedes-Benz 300SE spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What do I do if I see a pool of liquid under my Mercedes-Benz 300SE?

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.

What do hard starts and stops do to my 300SE engine?

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.

How frequently do I need to get my Mercedes-Benz 300SE fuel injectors cleaned?

The cleaning schedule for vehicle fuel injectors varies depending on your driving conditions and the type of fuel you use. Some manufacturers suggest cleaning your fuel system as part of routine maintenance, while others will recommend it on an as-needed basis if you’re experiencing poor performance. Reference your Mercedes-Benz owner’s manual for exact guidelines.

Tune-Ups to Help Your Mercedes-Benz 300SE Run Better

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, particularly if you want to keep your 1990 Mercedes-Benz 300SE in tip-top shape. Regular engine tune-ups can optimize your 300SE’s power on the road. Tune-ups help your engine start smoothly and run 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 300SE’s engine running smoother, longer.

Engine Tune-Up for Mercedes-Benz 300SE

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1990 Mercedes-Benz 300SE. The first is the standard Firestone Tune-Up. 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 300SE. 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 300SE's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your 300SE: 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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
