When should Mitsubishi Diamante 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 Diamante?

Don't ignore puddles of fluid under your Mitsubishi Diamante. 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 Mitsubishi Diamante 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.

Enhance Mitsubishi Diamante Performance with a Tune-Up

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you want your 2002 Mitsubishi Diamante’s engine to last for a long time. Regular engine tune-ups can optimize your Diamante’s power on the road. Tune-ups give your engine a boost in efficiency, 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 Mitsubishi, you invest in your Diamante's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Mitsubishi Diamante

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mitsubishi Diamante engine tune-up services. The standard Firestone Tune-Up is one service option. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. Another service option pays special attention to the filters in your Diamante. 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 Diamante’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 Diamante's mileage and maintenance history can uniquely impact its tune-up needs. If you’re not sure what services are the best fit for your car, let us help! Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
