Will it hurt my Subaru Legacy 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 Subaru’s recommendations.

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

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.

What do hard starts and stops do to my Legacy 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.

Subaru Legacy Engine Tune-Up Services

The Firestone Complete Auto Care location in your community offers several Subaru Legacy engine tune-up services. The standard Firestone Tune-Up is one service option.
