What happens if my Cadillac Eldorado 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 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?

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.

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you want your 1991 Cadillac Eldorado’s engine to last for a long time. 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, 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 Eldorado’s long-term engine performance.

Cadillac Eldorado Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Cadillac Eldorado engine tune-up services. The first is the standard Firestone Tune-Up. 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. 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 Eldorado. 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. If you’re not sure what services are the best fit for your car, let us help! Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
