Tune-Ups to Help Your GMC G2500 Run Better

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, especially if you drive a 1989 GMC G2500.

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 GMC's recommendations, you can rest assured you’re investing in your G2500’s long-term engine performance.

GMC G2500 Engine Tune-Up Services

The Firestone Complete Auto Care location in your community offers several GMC G2500 engine tune-up services. The first 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*. Another service option pays special attention to the filters in your G2500. Specifically, we replace the fuel filter and air 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 G2500. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your G2500: 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.

1989 GMC G2500 Engine Tune-Up Q&A

  • What happens if my GMC G2500 spark plugs fail? 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 should I do if I see leaks under my G2500? Don't ignore puddles of fluid under your GMC G2500. 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 G2500 engine than others? 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.
