When should Hyundai Sonata 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 should I do if I see leaks under my Sonata?

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 some driving habits better for my Hyundai Sonata 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.

Tune Into Your Hyundai Sonata

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, particularly if you want to keep your 1999 Hyundai Sonata in tip-top shape. Periodic tune-ups can bring more power back to your Sonata’s engine. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Hyundai's recommendations, you’re taking vital steps toward keeping your Sonata’s engine running smoother, longer.

Engine Tune-Up for Hyundai Sonata

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Hyundai Sonata engine tune-up services. The first is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. The second service focuses on your Sonata'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 Sonata. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your Sonata: your vehicle’s maintenance record and mileage can determine which service is best. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where to Get a Tune-Up for Your Hyundai Sonata

Come to Firestone Complete Auto Care for your next 1999 Sonata engine tune-up. Consult your vehicle’s recommended service schedule from Hyundai, or make a service appointment if you notice any of these symptoms from your engine: decreased gas mileage, "rough" idling or stalling when stopped, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
