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

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 does a puddle underneath my Cadillac CTS mean?

Don't ignore puddles of fluid under your Cadillac CTS. 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 hard starts and stops bad for my Cadillac CTS 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 CTS 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 could be time for a new way of doing things, particularly if you want to keep your 2003 Cadillac CTS in tip-top shape. Periodic tune-ups can bring more power back to your CTS’s engine. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by Cadillac for your vehicle’s tune-up schedule, you can rest assured you’re investing in your CTS’s long-term engine performance.

Engine Tune-Up for Cadillac CTS

The Firestone Complete Auto Care location in your community offers several Cadillac CTS 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 CTS. 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 CTS. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your CTS'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.

Where Should I Go for My Cadillac CTS Tune-Up?

If you’re looking for 2003 CTS engine tune-up services, head to Firestone Complete Auto Care. 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, engine knocking, or an illuminated check engine light.
