2004 Infiniti QX56 Tune-Up & Engine Service

Tune Into Your Infiniti QX56

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, it might be time to change your ways, especially if you want your 2004 Infiniti QX56’s engine to last for a long time. Routine engine tune-ups can bring power back to your QX56. 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 take your car for regular engine tune-ups as recommended by Infiniti, you’re taking vital steps toward keeping your QX56’s engine running smoother, longer.

Infiniti QX56 Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2004 Infiniti QX56. The standard Firestone Tune-Up is one service option. 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 QX56'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 QX56. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your QX56: 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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

2004 Infiniti QX56 Engine Tune-Up Q&A

  • What happens if my Infiniti QX56 spark plugs fail? 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 Infiniti’s recommendations.
  • What should I do if I see leaks under my QX56? 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 Infiniti QX56 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.
