When should Cadillac DeVille 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 Cadillac’s recommendations.

What does a puddle underneath my Cadillac DeVille mean?

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 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.

Tune-Ups to Help Your Cadillac DeVille Run Better

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 1983 Cadillac DeVille in tip-top shape. Regular engine tune-ups can optimize your DeVille’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 Cadillac, you invest in your DeVille's long-term health and engine performance.

Engine Tune-Up for Cadillac DeVille

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1983 Cadillac DeVille. 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 DeVille's filters, specifically replacing the air filter and fuel 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. 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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
