Enhance Saturn SL Performance with a Tune-Up

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, particularly if you want to keep your 1999 Saturn SL in tip-top shape. Routine engine tune-ups can bring power back to your SL. 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 Saturn, you invest in your SL's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Saturn SL

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Saturn SL engine tune-up services. The standard Firestone Tune-Up is one service option. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. The second service focuses on your SL's filters, specifically replacing the air filter and fuel filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your SL’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your SL'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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Come to Firestone Complete Auto Care for your next 1999 SL engine tune-up.

1999 Saturn SL Engine Tune-Up Q&A

  • Will it hurt my Saturn SL 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 does a puddle underneath my Saturn SL mean? 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 hard starts and stops bad for my Saturn SL engine? Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.
