Tune-Ups to Help Your Jeep Wrangler Run Better

Is it time for an engine 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, especially if you drive a 1989 Jeep Wrangler. Routine engine tune-ups can bring power back to your Wrangler. 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 Wrangler’s engine running smoother, longer.

Jeep Wrangler Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Jeep Wrangler 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 Wrangler. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your Wrangler's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your Wrangler'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 1989 Jeep Wranglers

  • What happens if my Jeep Wrangler 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 should I do if I see leaks under my Wrangler? 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 Wrangler engine? Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.
  • Where can I get a Jeep Wrangler tune-up? At your nearby Firestone Complete Auto Care! Whether you need Jeep Wrangler service, maintenance, or repairs, our technicians can get the job done.

Some manufacturers suggest cleaning your fuel system as part of routine maintenance, while others will recommend it on an as-needed basis if you’re experiencing poor performance. Reference your Jeep owner’s manual for exact guidelines.
