Tune-Ups to Help Your Jeep Grand Wagoneer Run Better

Is it time for an engine tune-up?

Routine engine tune-ups can bring power back to your Grand Wagoneer. 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 take your car for regular engine tune-ups as recommended by Jeep, you can rest assured you’re investing in your Grand Wagoneer’s long-term engine performance.

Jeep Grand Wagoneer Engine Tune-Up Services

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 first is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. 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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Common Engine Tune-Up Q&A For 1985 Jeep Grand Wagoneers

  • When should Jeep Grand Wagoneer spark plugs be replaced? 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 does a puddle underneath my Jeep Grand Wagoneer mean? 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 Grand Wagoneer 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.
