When should Mercedes-Benz SLK350 spark plugs be replaced?

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 do I do if I see a pool of liquid under my Mercedes-Benz SLK350?

Don't ignore puddles of fluid under your Mercedes-Benz SLK350. 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.

Are some driving habits better for my Mercedes-Benz SLK350 engine than others?

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.

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2009 Mercedes-Benz SLK350. One option is the standard Firestone Tune-Up.

The second service focuses on your SLK350's filters, specifically replacing the air filter and fuel 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 SLK350's fuel injectors, throttle body, and throttle plate.
