Will it hurt my Cadillac CT5 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 do I do if I see a pool of liquid under my Cadillac CT5?

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.

Are some driving habits better for my Cadillac CT5 engine than others?

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.

How often should I clean my Cadillac CT5 fuel injectors?

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 CT5 Run Better

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, especially if you want your 2021 Cadillac CT5’s engine to last for a long time. Regular engine tune-ups can optimize your CT5’s power on the road. They're designed to help your engine start easier and run more efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you take your car for regular engine tune-ups as recommended by Cadillac, you can rest assured you’re investing in your CT5’s long-term engine performance.

Engine Tune-Up for Cadillac CT5

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Cadillac CT5 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*. Another service option pays special attention to the filters in your CT5. Specifically, we replace the fuel filter and air filter. 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 CT5. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your CT5: 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 to Get a Cadillac CT5 Tune-Up

Use Cadillac’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: stalling or shaky idling when you’re stopped, diminished fuel economy, engine knocking, or an illuminated check engine light.
