When should GMC Terrain spark plugs be replaced?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What do I do if I see a pool of liquid under my GMC Terrain?

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 GMC Terrain engine?

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.

Enhance GMC Terrain Performance with a Tune-Up

Is it tune-up time? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you want your 2021 GMC Terrain’s engine to last for a long time. Routine engine tune-ups can bring power back to your Terrain. Tune-ups give your engine a boost in efficiency, 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 GMC for your vehicle’s tune-up schedule, you invest in your Terrain's long-term health and engine performance.

GMC Terrain Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to GMC Terrain 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 Terrain's filters, specifically replacing the air filter and fuel filter. 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 Terrain's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your Terrain: your vehicle’s maintenance record and mileage can determine which service is best. If you’re not sure what services are the best fit for your car, let us help! Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
