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?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are some driving habits better for my Cadillac DeVille 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.

How often should I clean my Cadillac DeVille fuel injectors?

Some manufacturers generally recommend a fuel system cleaning as part of your general car maintenance, or as needed based on symptoms of poor fuel system performance.

Enhance Cadillac DeVille Performance with a Tune-Up

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, particularly if you want to keep your 2003 Cadillac DeVille in tip-top shape. Routine engine tune-ups can bring power back to your DeVille. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Cadillac, you’re taking vital steps toward keeping your DeVille’s engine running smoother, longer.

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2003 Cadillac DeVille. The standard Firestone Tune-Up is one service option. 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.

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 DeVille can determine what kind of service it needs.
