When should Jeep Grand Cherokee L spark plugs be replaced?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

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

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 Grand Cherokee L 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.

Tune Into Your Jeep Grand Cherokee L

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, especially if you want your 2021 Jeep Grand Cherokee L’s engine to last for a long time. Routine engine tune-ups can bring power back to your Grand Cherokee L. Tune-ups give your engine a boost in efficiency, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you get routine engine tune-ups based on Jeep's recommendations, you invest in your Grand Cherokee L's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Jeep Grand Cherokee L

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Jeep Grand Cherokee L engine tune-up services. The first 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*. The second service focuses on your Grand Cherokee L's filters, specifically replacing the air filter and fuel filter. 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 Cherokee L. 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 Cherokee L can determine what kind of service it 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.
