What happens if my Mercedes-Benz CL550 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 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?

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.

How often should I clean my Mercedes-Benz CL550 fuel injectors?

Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

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

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you want your 2014 Mercedes-Benz CL550’s engine to last for a long time. Routine engine tune-ups can bring power back to your CL550. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. 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.

Routine Engine Tune-Up Service for Your Mercedes-Benz CL550

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2014 Mercedes-Benz CL550. The standard Firestone Tune-Up is one service option. 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 CL550. 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. Keep in mind that your CL550's mileage and maintenance history can uniquely impact its tune-up needs. 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.

Where Should I Go for My Mercedes-Benz CL550 Tune-Up?

Come to Firestone Complete Auto Care for your next 2014 CL550 engine tune-up. Consult your vehicle’s recommended service schedule from Mercedes-Benz, or make a service appointment if you notice any of these symptoms from your engine: shaking while the engine is idling, poor fuel economy, engine knocking, or an illuminated check engine light.
