What happens if my Cadillac DeVille spark plugs fail?

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 starts and stops put extra wear and tear on engine components. Smooth, gradual starts and stops, on the other hand, are a great way to help your engine run better. They can also help maximize your fuel economy.

Tune Into Your Cadillac DeVille

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 might be time to change your ways, especially if you want your 1999 Cadillac DeVille’s engine to last for a long time. Regular engine tune-ups can optimize your DeVille’s power on the road. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you follow the guidelines specified by Cadillac for your vehicle’s tune-up schedule, 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. The standard Firestone Tune-Up is one service option. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your DeVille. 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. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your DeVille: 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.
