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 do I do if I see a pool of liquid under my Cadillac 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 some driving habits better for my Cadillac DeVille engine than others?

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 DeVille

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, especially if you want your 1985 Cadillac DeVille’s engine to last for a long time. Periodic tune-ups can bring more power back to your DeVille’s engine. Tune-ups help your engine start smoothly and run 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’re taking vital steps toward keeping your DeVille’s engine running smoother, longer.

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 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. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your DeVille’s fuel injectors, throttle body, and throttle plate. 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. 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?

Schedule your next 1985 DeVille engine tune-up service at Firestone Complete Auto Care. Follow Cadillac's recommended maintenance schedule or book an appointment as soon as you notice one of the following: stalling or shaky idling when you’re stopped, diminished fuel economy, knocking noises in the engine, or a lit up check engine light on your dashboard.
