Will it hurt my Mercedes-Benz CL550 to drive with old spark plugs?

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 should I do if I see leaks under my CL550?

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.

Are hard starts and stops bad for my Mercedes-Benz CL550 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.

Tune-Ups to Help Your Mercedes-Benz CL550 Run Better

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, particularly if you want to keep your 2011 Mercedes-Benz CL550 in tip-top shape. Regular engine tune-ups can optimize your CL550’s power on the road. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions. When you follow the guidelines specified by Mercedes-Benz for your vehicle’s tune-up schedule, you can rest assured you’re investing in your CL550’s long-term engine performance.

Engine Tune-Up for Mercedes-Benz CL550

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz CL550 engine tune-up services. 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*. Another service option pays special attention to the filters in your CL550. Specifically, we replace the fuel filter and air filter. 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 CL550'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 CL550: your vehicle’s maintenance record and mileage can determine which service is best. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
