Tune-Ups to Help Your Jeep Grand Wagoneer Run Better

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, particularly if you want to keep your 1989 Jeep Grand Wagoneer in tip-top shape. Regular engine tune-ups can optimize your Grand Wagoneer’s power on the road. 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 can rest assured you’re investing in your Grand Wagoneer’s long-term engine performance.

Routine Engine Tune-Up Service for Your Jeep Grand Wagoneer

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Jeep Grand Wagoneer engine tune-up services. The standard Firestone Tune-Up is one service option. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. Another service option pays special attention to the filters in your Grand Wagoneer. Specifically, we replace the fuel filter and air 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. This can improve your fuel system’s performance (and therefore, your engine’s performance). Here’s something to remember when choosing services: the mileage and service history of your Grand Wagoneer can determine what kind of service it needs. 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.

Common Engine Tune-Up Q&A For 1989 Jeep Grand Wagoneers

  • 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 do I do if I see a pool of liquid under my Jeep Grand Wagoneer? Don't ignore puddles of fluid under your Jeep Grand Wagoneer. 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 Grand Wagoneer 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.
