When should Cadillac DeVille spark plugs be replaced?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What do I do if I see a pool of liquid under my Cadillac DeVille?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

What do hard starts and stops do to my DeVille engine?

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.

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 1994 Cadillac DeVille in tip-top shape. Periodic tune-ups can bring more power back to your DeVille’s engine. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Cadillac's recommendations, you’re taking vital steps toward keeping your DeVille’s engine running smoother, longer.

Engine Tune-Up for 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. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. Another service option pays special attention to the filters in your DeVille. Specifically, we replace the fuel filter and air filter. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your DeVille's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s 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. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. 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 1994 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, engine knocking, or an illuminated check engine light.

*Ask a Firestone Complete Auto Care teammate about full terms and conditions for warranties.
