Tune Into Your Hyundai Sonata

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, especially if you want your 2003 Hyundai Sonata’s engine to last for a long time. Routine engine tune-ups can bring power back to your Sonata. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Hyundai's recommendations, you can rest assured you’re investing in your Sonata’s long-term engine performance.

Hyundai Sonata Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Hyundai Sonata engine tune-up services. The standard Firestone Tune-Up is one service option. 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 Sonata. 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 Sonata. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your Sonata can determine what kind of service it needs. If you’re not sure what services are the best fit for your car, let us help! Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

Common Engine Tune-Up Q&A For 2003 Hyundai Sonatas

  • Will it hurt my Hyundai Sonata to drive with old spark plugs? Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.
  • What do I do if I see a pool of liquid under my Hyundai Sonata? Don't ignore puddles of fluid under your Hyundai Sonata. 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 Sonata 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.
