What happens if my Jeep Grand Cherokee 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 should I do if I see leaks under my Grand Cherokee?

Don't ignore puddles of fluid under your Jeep Grand Cherokee. 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 Cherokee 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.

Enhance Jeep Grand Cherokee Performance with a Tune-Up

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you want your 2009 Jeep Grand Cherokee’s engine to last for a long time. Regular engine tune-ups can optimize your Grand Cherokee’s power on the road. 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 invest in your Grand Cherokee's long-term health and engine performance.

Jeep Grand Cherokee Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Jeep Grand Cherokee engine tune-up services. One option is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your Grand Cherokee. 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 Cherokee’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your Grand Cherokee's mileage and maintenance history can uniquely impact its tune-up needs. 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.

Where Should I Go for My Jeep Grand Cherokee Tune-Up?

Schedule your next 2009 Grand Cherokee engine tune-up service at Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Jeep, or make a service appointment if you notice any of these symptoms from your engine: stalling or shaky idling when you’re stopped, diminished fuel economy, knocking noises in the engine, or a lit up check engine light on your dashboard.
