1984 Jeep Grand Wagoneer Tune-Up & Engine Service

Tune Into Your Jeep Grand Wagoneer

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, especially if you want your 1984 Jeep Grand Wagoneer’s engine to last for a long time. Periodic tune-ups can bring more power back to your Grand Wagoneer’s engine. Tune-ups help your engine start smoothly and run 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 invest in your Grand Wagoneer's long-term health and engine performance.

Engine Tune-Up for 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 first is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your Grand Wagoneer. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your Grand Wagoneer. This goes a long way in boosting your fuel system’s overall 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. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

1984 Jeep Grand Wagoneer Engine Tune-Up Q&A

  • Will it hurt my Jeep Grand Wagoneer to drive with old spark plugs? 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? 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.
  • What do hard starts and stops do to my Grand Wagoneer engine? You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.
