Periodic tune-ups can bring more power back to your C2500 Suburban’s engine. 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).

GMC C2500 Suburban Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1986 GMC C2500 Suburban. 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*. Another service option pays special attention to the filters in your C2500 Suburban. Specifically, we replace the fuel filter and air filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your C2500 Suburban’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 C2500 Suburban'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.

Common Engine Tune-Up Q&A For 1986 GMC C2500 Suburbans

  • Will it hurt my GMC C2500 Suburban 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 GMC’s recommendations.
  • What do I do if I see a pool of liquid under my GMC C2500 Suburban? Don't ignore puddles of fluid under your GMC C2500 Suburban. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.
  • Are some driving habits better for my GMC C2500 Suburban engine than others? 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.
