Tune Into Your Lexus GS300

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, particularly if you want to keep your 2004 Lexus GS300 in tip-top shape. Regular engine tune-ups can optimize your GS300’s power on the road. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions. When you follow the guidelines specified by Lexus for your vehicle’s tune-up schedule, you invest in your GS300's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Lexus GS300

The Firestone Complete Auto Care location in your community offers several Lexus GS300 engine tune-up services. One option is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. Another service option pays special attention to the filters in your GS300. Specifically, we replace the fuel filter and air 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 GS300’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 GS300'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.

2004 Lexus GS300 Engine Tune-Up Q&A

  • When should Lexus GS300 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 Lexus’s recommendations.
  • What do I do if I see a pool of liquid under my Lexus GS300? Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.
  • Are hard starts and stops bad for my Lexus GS300 engine? 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.
