Tune Into Your GMC S15 Jimmy

Is it time for an engine tune-up? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, especially if you want your 1989 GMC S15 Jimmy’s engine to last for a long time. Periodic tune-ups can bring more power back to your S15 Jimmy’s engine. 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 get routine engine tune-ups based on GMC's recommendations, you can rest assured you’re investing in your S15 Jimmy’s long-term engine performance.

Engine Tune-Up for GMC S15 Jimmy

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to GMC S15 Jimmy engine tune-up services. One option is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. Another service option pays special attention to the filters in your S15 Jimmy. 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 S15 Jimmy. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your S15 Jimmy: your vehicle’s maintenance record and mileage can determine which service is best. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Common Engine Tune-Up Q&A For 1989 GMC S15 Jimmys

  • What happens if my GMC S15 Jimmy spark plugs fail? 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 does a puddle underneath my GMC S15 Jimmy mean? Don't ignore puddles of fluid under your GMC S15 Jimmy. 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 S15 Jimmy 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.
