What happens if my Cadillac Eldorado spark plugs fail?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

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

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 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.

Where can I get a tune-up for my Cadillac Eldorado?

How often should I clean my Cadillac Eldorado fuel injectors?

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Tune Into Your Cadillac Eldorado

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you want your 1986 Cadillac Eldorado’s engine to last for a long time. Routine engine tune-ups can bring power back to your Eldorado. 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

The Firestone Complete Auto Care location in your community offers several Cadillac Eldorado engine tune-up services. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. 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. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where to Get a Cadillac Eldorado Tune-Up

Come to Firestone Complete Auto Care for your next 1986 Eldorado engine tune-up. Consult your vehicle’s recommended service schedule from Cadillac, or make a service appointment if you notice any of these symptoms from your engine: shaking while the engine is idling, poor fuel economy, engine knocking, or an illuminated check engine light.
