2004 Infiniti Q45 Tune-Up & Engine Service

Tune Into Your Infiniti Q45

Is your engine overdue for a tune-up? 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 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, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Infiniti, you’re taking vital steps toward keeping your Q45’s engine running smoother, longer.

Engine Tune-Up for Infiniti Q45

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Infiniti Q45 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 Q45. Specifically, we replace the fuel filter and air filter. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your Q45's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s 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.

2004 Infiniti Q45 Engine Tune-Up Q&A

  • What happens if my Infiniti Q45 spark plugs fail? When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.
  • What does a puddle underneath my Infiniti Q45 mean? 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 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.
