Will it hurt my Mitsubishi Galant 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 Mitsubishi’s recommendations.

What should I do if I see leaks under my Galant?

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 Mitsubishi Galant engine than others?

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.

How frequently do the fuel injectors in my Mitsubishi Galant need to be cleaned?

Enhance Mitsubishi Galant Performance with a Tune-Up

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, it might be time to change your ways, especially if you drive a 2003 Mitsubishi Galant. Regular engine tune-ups can optimize your Galant’s power on the road. Tune-ups help your engine start smoothly and run efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you follow the guidelines specified by Mitsubishi for your vehicle’s tune-up schedule, you invest in your Galant's long-term health and engine performance.

Mitsubishi Galant Engine Tune-Up Services

The Firestone Complete Auto Care location in your community offers several Mitsubishi Galant 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 Galant. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your Galant'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 Galant'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 Should I Go for My Mitsubishi Galant Tune-Up?

Schedule your next 2003 Galant engine tune-up service at Firestone Complete Auto Care. Follow Mitsubishi's recommended maintenance schedule or book an appointment as soon as you notice one of the following: shaking while the engine is idling, poor fuel economy, engine knocking, or an illuminated check engine light.
