Tune-Ups to Help Your Jeep CJ7 Run Better

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, particularly if you want to keep your 1986 Jeep CJ7 in tip-top shape. Periodic tune-ups can bring more power back to your CJ7’s engine. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you follow the guidelines specified by Jeep for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your CJ7’s engine running smoother, longer.

Engine Tune-Up for Jeep CJ7

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1986 Jeep CJ7. One option is the standard Firestone Tune-Up.

Another service option pays special attention to the filters in your CJ7. Specifically, we replace the fuel filter and air filter.

The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your CJ7 can determine what kind of service it needs.

Common Engine Tune-Up Q&A For 1986 Jeep CJ7s

  • Will it hurt my Jeep CJ7 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 do I do if I see a pool of liquid under my Jeep CJ7? 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 CJ7 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.
