When should Mercedes-Benz CL550 spark plugs be replaced?

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 should I do if I see leaks under my CL550?

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.

Are hard starts and stops bad for my Mercedes-Benz CL550 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 the fuel injectors in my Mercedes-Benz CL550 need to be cleaned?

Tune-Ups to Help Your Mercedes-Benz CL550 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, especially if you drive a 2008 Mercedes-Benz CL550. Regular engine tune-ups can optimize your CL550’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 get routine engine tune-ups based on Mercedes-Benz's recommendations, you can rest assured you’re investing in your CL550’s long-term engine performance.

Engine Tune-Up for Mercedes-Benz CL550

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz CL550 engine tune-up services. One option 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 CL550. 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 CL550’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your CL550 can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. 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?

If you’re looking for 2008 CL550 engine tune-up services, head to Firestone Complete Auto Care. Not sure when you’re due for a tune-up? Use Mercedes-Benz’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: shaking while the engine is idling, poor fuel economy, engine knocking, or an illuminated check engine light.
