Tune-Ups to Help Your Infiniti Q45 Run Better

Is it time for an engine tune-up? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, especially if you want your 2002 Infiniti Q45’s engine to last for a long time. Regular engine tune-ups can optimize your Q45’s power on the road. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you follow the guidelines specified by Infiniti for your vehicle’s tune-up schedule, you invest in your Q45's long-term health and engine performance.

Infiniti Q45 Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Infiniti Q45 engine tune-up services. 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*. Another service option pays special attention to the filters in your Q45. Specifically, we replace the fuel filter and air filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your Q45’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your Q45's mileage and maintenance history can uniquely impact its tune-up needs. 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 Infiniti Q45

2002 Infiniti Q45 Engine Tune-Up Q&A

  • Will it hurt my Infiniti Q45 to drive with old spark plugs? 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 Q45? Don't ignore puddles of fluid under your Infiniti Q45. 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 hard starts and stops bad for my Infiniti Q45 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.
