1986 Jeep J20 Engine Tune-Ups & Maintenance

Tune Into Your Jeep J20

Is your engine overdue for a 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, particularly if you want to keep your 1986 Jeep J20 in tip-top shape. Regular engine tune-ups can optimize your J20’s power on the road. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Jeep, you’re taking vital steps toward keeping your J20’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your 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. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your J20. 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 J20’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your J20's mileage and maintenance history can uniquely impact its tune-up needs. If you’re not sure what services are the best fit for your car, let us help! Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

Questions About 1986 Jeep J20 Engine Tune-Ups

  • Will it hurt my Jeep J20 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 Jeep’s recommendations.
  • What does a puddle underneath my Jeep J20 mean? Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.
  • Are hard starts and stops bad for my Jeep J20 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.
