What happens if my Cadillac DTS 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 DTS?

Don't ignore puddles of fluid under your Cadillac DTS. 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.

What do hard starts and stops do to my DTS 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 Into Your Cadillac DTS

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, particularly if you want to keep your 2006 Cadillac DTS in tip-top shape. Routine engine tune-ups can bring power back to your DTS. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions. When you take your car for regular engine tune-ups as recommended by Cadillac, you invest in your DTS's long-term health and engine performance.

Cadillac DTS Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Cadillac DTS engine tune-up services. One option 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 DTS. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your DTS's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your DTS: your vehicle’s maintenance record and mileage can determine which service is best. 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 Should I Go for My Cadillac DTS Tune-Up?

Come to Firestone Complete Auto Care for your next 2006 DTS engine tune-up. Follow Cadillac's recommended maintenance schedule or book an appointment as soon as you notice one of the following: decreased gas mileage, "rough" idling or stalling when stopped, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
