When should Subaru Legacy 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 Subaru’s recommendations.

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

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.

What do hard starts and stops do to my Legacy 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.

Tune-Ups to Help Your Subaru Legacy Run Better

Is it tune-up time? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you want your 2003 Subaru Legacy’s engine to last for a long time. Periodic tune-ups can bring more power back to your Legacy’s engine. 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 get routine engine tune-ups based on Subaru's recommendations, you’re taking vital steps toward keeping your Legacy’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Subaru Legacy

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Subaru Legacy 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*. The second service focuses on your Legacy's filters, specifically replacing the air filter and fuel 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 Legacy. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your Legacy'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.
