Will it hurt my Kia Carnival to drive with old spark plugs?

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 Kia’s recommendations.

What should I do if I see leaks under my Carnival?

Don't ignore puddles of fluid under your Kia Carnival. 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 some driving habits better for my Kia Carnival engine than others?

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.

Where can I have a Kia Carnival tune-up done?

How frequently do I need to get my Kia Carnival fuel injectors cleaned?

The cleaning schedule for vehicle fuel injectors varies depending on your driving conditions and the type of fuel you use. Some manufacturers suggest cleaning your fuel system as part of routine maintenance, while others will recommend it on an as-needed basis if you’re experiencing poor performance. Reference your Kia owner’s manual for exact guidelines.

Tune Into Your Kia Carnival

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, especially if you drive a 2025 Kia Carnival. Routine engine tune-ups can bring power back to your Carnival. 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 Kia for your vehicle’s tune-up schedule, you invest in your Carnival's long-term health and engine performance.

Kia Carnival Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Kia Carnival 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*. Another service option pays special attention to the filters in your Carnival. Specifically, we replace the fuel filter and air 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 Carnival. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your Carnival: your vehicle’s maintenance record and mileage can determine which service is best. If you’re not sure what services are the best fit for your car, let us help! Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
