Will it hurt my Cadillac XT6 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 Cadillac’s recommendations.

What should I do if I see leaks under my XT6?

Don't ignore puddles of fluid under your Cadillac XT6. 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.

What do hard starts and stops do to my XT6 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.

Tune Into Your Cadillac XT6

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, especially if you want your 2021 Cadillac XT6’s engine to last for a long time. Periodic tune-ups can bring more power back to your XT6’s engine. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Cadillac's recommendations, you invest in your XT6's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Cadillac XT6

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Cadillac XT6 engine tune-up services. The first is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. The second service focuses on your XT6'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 XT6's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your XT6: 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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where Should I Go for My Cadillac XT6 Tune-Up?
