Tune-Ups to Help Your GMC S15 Jimmy 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, it might be time to change your ways, particularly if you want to keep your 1985 GMC S15 Jimmy in tip-top shape. Routine engine tune-ups can bring power back to your S15 Jimmy. 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 follow the guidelines specified by GMC for your vehicle’s tune-up schedule, you can rest assured you’re investing in your S15 Jimmy’s long-term engine performance.

Engine Tune-Up for GMC S15 Jimmy

The Firestone Complete Auto Care location in your community offers several GMC S15 Jimmy engine tune-up services. 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*. A second service option replaces the air and fuel filter in your S15 Jimmy. 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). Here’s something to remember when choosing services: the mileage and service history of your S15 Jimmy can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. 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 1985 GMC S15 Jimmys

  • Will it hurt my GMC S15 Jimmy to drive with old spark plugs? Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.
  • What do I do if I see a pool of liquid under my GMC S15 Jimmy? 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.
  • What do hard starts and stops do to my S15 Jimmy engine? 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.
