Will it hurt my Cadillac STS to drive with old spark plugs?

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 does a puddle underneath my Cadillac STS mean?

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.

Are hard starts and stops bad for my Cadillac STS 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 STS Run Better

Is it time for an engine tune-up? 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 2006 Cadillac STS’s engine to last for a long time. Periodic tune-ups can bring more power back to your STS’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 get routine engine tune-ups based on Cadillac's recommendations, you’re taking vital steps toward keeping your STS’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your 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. The first is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your STS. 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 STS. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your STS: your vehicle’s maintenance record and mileage can determine which service is best. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where to Get a Cadillac STS Tune-Up

Schedule your next 2006 STS engine tune-up service at Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Cadillac, or make a service appointment if you notice any of these symptoms from your engine: stalling or shaky idling when you’re stopped, diminished fuel economy, engine knocking, or an illuminated check engine light.
