What happens if my Cadillac STS spark plugs fail?

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 does a puddle underneath my Cadillac STS mean?

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

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

How frequently do I need to get my Cadillac STS fuel injectors cleaned?

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-Ups to Help Your Cadillac STS Run Better

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, especially if you drive a 2007 Cadillac STS. Regular engine tune-ups can optimize your STS’s power on the road. Tune-ups give your engine a boost in efficiency, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you follow the guidelines specified by Cadillac for your vehicle’s tune-up schedule, you invest in your STS's long-term health and engine performance.

Engine Tune-Up for Cadillac STS

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Cadillac STS engine tune-up services. One option 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*. A second service option replaces the air and fuel filter in your STS. 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 STS’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your STS'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! Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
