Tune Into Your GMC S15

Is it time for an engine tune-up?

Regular engine tune-ups can optimize your S15’s power on the road. They're designed to help your engine start easier and run more 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 GMC's recommendations, you’re taking vital steps toward keeping your S15’s engine running smoother, longer.

GMC S15 Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1983 GMC S15. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. The second service focuses on your S15'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 S15. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your S15: your vehicle’s maintenance record and mileage can determine which service is best. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
