What happens if my Cadillac XT4 spark plugs fail?

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 should I do if I see leaks under my XT4?

Don't ignore puddles of fluid under your Cadillac XT4. 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 XT4 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.

Enhance Cadillac XT4 Performance with a Tune-Up

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you drive a 2021 Cadillac XT4. Regular engine tune-ups can optimize your XT4’s power on the road. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Cadillac's recommendations, you’re taking vital steps toward keeping your XT4’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Cadillac XT4

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Cadillac XT4 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 XT4. 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 XT4. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your XT4'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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

Where to Get a Tune-Up for Your Cadillac XT4
