Engine Tune-Up for Jeep J20

The Firestone Complete Auto Care location in your community offers several Jeep J20 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*. A second service option replaces the air and fuel filter in your J20. 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 J20. The result? Restored fuel system performance. Keep in mind that your J20's mileage and maintenance history can uniquely impact its tune-up needs. 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 1983 Jeep J20s

  • When should Jeep J20 spark plugs be replaced? 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 does a puddle underneath my Jeep J20 mean? Don't ignore puddles of fluid under your Jeep J20. 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 hard starts and stops bad for my Jeep J20 engine? 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.
  • Where can I get a Jeep J20 tune-up? At your nearby Firestone Complete Auto Care! Whether you need Jeep J20 service, maintenance, or repairs, our technicians can get the job done.

Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.
