When should Jeep Wrangler spark plugs be replaced?

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 Wrangler mean?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are hard starts and stops bad for my Jeep Wrangler 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-Ups to Help Your Jeep Wrangler Run Better

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you drive a 2003 Jeep Wrangler. Regular engine tune-ups can optimize your Wrangler’s power on the road. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Jeep, you can rest assured you’re investing in your Wrangler’s long-term engine performance.

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2003 Jeep Wrangler. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. Another service option pays special attention to the filters in your Wrangler. Specifically, we replace the fuel filter and air filter.

The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your Wrangler can determine what kind of service it needs.
