Will it hurt my Cadillac DeVille 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 DeVille?

Don't ignore puddles of fluid under your Cadillac DeVille. 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 hard starts and stops bad for my Cadillac DeVille 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.

Tune Into Your Cadillac DeVille

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, particularly if you want to keep your 1998 Cadillac DeVille in tip-top shape. Regular engine tune-ups can optimize your DeVille’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 Cadillac's recommendations, you can rest assured you’re investing in your DeVille’s long-term engine performance.

Routine Engine Tune-Up Service for Your Cadillac DeVille

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Cadillac DeVille engine tune-up services. One option 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*. Another service option pays special attention to the filters in your DeVille. Specifically, we replace the fuel filter and air filter. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your DeVille. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your DeVille can determine what kind of service it 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 Cadillac DeVille Tune-Up?
