Engine Tune-Up Service for Your 1986 Jeep Grand Wagoneer

Tune-Ups to Help Your Jeep Grand Wagoneer Run Better

Is it tune-up time? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you drive a 1986 Jeep Grand Wagoneer. Regular engine tune-ups can optimize your Grand Wagoneer’s power on the road. Tune-ups help your engine start smoothly and run 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 Grand Wagoneer’s engine running smoother, longer.

Jeep Grand Wagoneer Engine Tune-Up Services

The Firestone Complete Auto Care location in your community offers several Jeep Grand Wagoneer engine tune-up services. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. The second service focuses on your Grand Wagoneer's filters, specifically replacing the air filter and fuel filter. 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 Grand Wagoneer’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your Grand Wagoneer: your vehicle’s maintenance record and mileage can determine which service is best. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

1986 Jeep Grand Wagoneer Engine Tune-Up Q&A

  • What happens if my Jeep Grand Wagoneer spark plugs fail? 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 should I do if I see leaks under my Grand Wagoneer? 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 some driving habits better for my Jeep Grand Wagoneer engine than others? 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.
