What happens if my Cadillac Seville 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 Seville?

Don't ignore puddles of fluid under your Cadillac Seville. 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 Seville engine than others?

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 Seville Run Better

Is it tune-up time? 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 want your 2003 Cadillac Seville’s engine to last for a long time. Regular engine tune-ups can optimize your Seville’s power on the road. 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 can rest assured you’re investing in your Seville’s long-term engine performance.

Engine Tune-Up for Cadillac Seville

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Cadillac Seville 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*. The second service focuses on your Seville'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 Seville’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your Seville'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. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
