Will it hurt my Cadillac Eldorado 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 does a puddle underneath my Cadillac Eldorado mean?

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 hard starts and stops bad for my Cadillac Eldorado 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-Ups to Help Your Cadillac Eldorado Run Better

Is your engine overdue for a tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, especially if you drive a 1983 Cadillac Eldorado. Periodic tune-ups can bring more power back to your Eldorado’s engine. They're designed to help your engine start easier and run more efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you get routine engine tune-ups based on Cadillac's recommendations, you’re taking vital steps toward keeping your Eldorado’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Cadillac Eldorado

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1983 Cadillac Eldorado. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. Another service option pays special attention to the filters in your Eldorado. Specifically, we replace the fuel filter and air 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 Eldorado’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your Eldorado's mileage and maintenance history can uniquely impact its tune-up needs. 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.

Come to Firestone Complete Auto Care for your next 1983 Eldorado engine tune-up. Not sure when you’re due for a tune-up? Use Cadillac’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: decreased gas mileage, "rough" idling or stalling when stopped, knocking noises in the engine, or a lit up check engine light on your dashboard.
