When should Mercedes-Benz GLS450 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 GLS450?

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 GLS450 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.

Enhance Mercedes-Benz GLS450 Performance with a Tune-Up

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 2022 Mercedes-Benz GLS450 in tip-top shape. Regular engine tune-ups can optimize your GLS450’s power on the road. Tune-ups give your engine a boost in efficiency, 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 GLS450’s engine running smoother, longer.

Engine Tune-Up for Mercedes-Benz GLS450

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz GLS450 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*. The second service focuses on your GLS450'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 GLS450'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 GLS450 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 GLS450 Tune-Up?
