What happens if my Jeep Wagoneer spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Jeep’s recommendations.

What does a puddle underneath my Jeep 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.

Are hard starts and stops bad for my Jeep 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.

Tune Into Your Jeep Wagoneer

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, it might be time to change your ways, particularly if you want to keep your 1986 Jeep Wagoneer in tip-top shape. Routine engine tune-ups can bring power back to your Wagoneer. They're designed to help your engine start easier and run more efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you follow the guidelines specified by Jeep for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your Wagoneer’s engine running smoother, longer.

Jeep Wagoneer Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Jeep Wagoneer engine tune-up services. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your 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 Wagoneer. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your Wagoneer'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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where to Get a Tune-Up for Your Jeep Wagoneer

Schedule your next 1986 Wagoneer engine tune-up service at Firestone Complete Auto Care. Not sure when you’re due for a tune-up? Use Jeep’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: decreased gas mileage, "rough" idling or stalling when stopped, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.

*Ask a Firestone Complete Auto Care teammate about full terms and conditions for warranties.
