Will it hurt my Jeep Grand Cherokee to drive with old spark plugs?

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?

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 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

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you drive a 1994 Jeep Grand Cherokee. Routine engine tune-ups can bring power back to your Grand Cherokee. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Jeep's recommendations, you can rest assured you’re investing in your Grand Cherokee’s long-term engine performance.

Routine Engine Tune-Up Service for Your Jeep Grand Cherokee

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1994 Jeep Grand Cherokee. 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 Cherokee'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. 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 can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

Where to Get a Jeep Grand Cherokee Tune-Up

If you’re looking for 1994 Grand Cherokee engine tune-up services, head to 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: shaking while the engine is idling, poor fuel economy, knocking noises in the engine, or a lit up check engine light on your dashboard.
