When should Cadillac CTS spark plugs be replaced?

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 CTS?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

What do hard starts and stops do to my CTS engine?

You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.

Tune-Ups to Help Your Cadillac CTS Run Better

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you want your 2018 Cadillac CTS’s engine to last for a long time. Periodic tune-ups can bring more power back to your CTS’s engine. Tune-ups help your engine start smoothly and run efficiently, 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 CTS's long-term health and engine performance.

Routine Engine Tune-Up Service for Your 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*. Another service option pays special attention to the filters in your CTS. Specifically, we replace the fuel filter and air filter. 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 CTS'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 CTS's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
